Pesticide Application

Plant protection activities are most important practices during crop production. Application of maximum pesticide products with the sprayer. The application of fungicides, herbicides, and insecticides is one of the most recurrent and significant tasks in agriculture. Conventional agricultural spraying techniques have made the inconsistency between economic growth and environmental protection in agricultural production. Spraying techniques continuously developed in recent decades. For pesticide application, it is not the only sprayer that is essential, but all the parameters like the type and area of the plant canopy, area of a plant leaf, height of the crop, and volume of plants related to plant protection product applications are very important for obtaining better results. From this point of view, the advancement in agriculture sprayer has been started in last few decades. Robotics and automatic spraying technologies like variable rate sprayers, UAV sprayers, and electrostatic sprayers are growing to Increase the utilization rate of pesticides, reduce pesticide residues, real-time, cost-saving, high compatibility of plant protection products application. These technologies are under the “umbrella” of precision agriculture. The mechanized spraying system, usually implemented by highly precise equipment or mobile robots, which, makes possible the selective targeting of pesticide application on desire time and place. These advanced spraying technologies not only reduces the labour cost but also effective in environmental protection. Researchers are conducting experimental studies on the design, development and testing of precision spraying technologies for crops and orchards.

Spray System

AbstractThe pulse width modulation (PWM) spray system is the most advanced technology to obtain variable rate spray application without varying the operative sprayer parameters (e.g. spray pressure, nozzle size). According to the precision agriculture principles, PWM is the prime technology that allows to spray the required amount where needed without varying the droplet size spectra which benefits both the uniformity of spray quality and the spray drift reduction. However, some concerns related to the effect of on–off solenoid valves and the alternating on/off action of adjacent nozzles on final uneven spray coverage (SC) have arisen. Further evaluations of PWM systems used for spraying 3D crops under field conditions are welcomed. A tower-shaped airblast sprayer equipped with a PWM was tested in a vineyard. Twelve configurations, combining duty cycles (DC: 30, 50, 70, 100%) and forward speeds (FS: 4, 6, 8 km h−1), were tested. Two methodologies, namely field-standardized and real field conditions, were adopted to evaluate the effect of DC and FS on (1) SC variability (CV%) along both the sprayer travel direction and the vertical spray profile using long water sensitive papers (WSP), and (2) SC uniformity (IU, index value) within the canopy at different depths and heights, respectively. Furthermore, the SC (%) and deposit density (Nst, no stains cm−2), determined using short WSP, were used to evaluate the spray application performances taking into account the spray volumes applied. Under field-controlled conditions, the pulsing of the PWM system affects both the SC variability measured along the sprayer travel direction and along the vertical spray profile. In contrast, under real field conditions, the PWM system does not affect the uniformity of SC measured within the canopy. The relationship between SC and Nst allowed identification of the ranges of 200–250 and 300–370 l ha−1 as the most suitable spray volumes to be applied for insecticide and fungicide plant protection products, respectively.

The right way out of the crisis of the agro-based industries is the maximum use of the opportunities of scientific and technological progress and the orientation of the real economy to innovative development. One of the promising technologies of crop production is an innovative technology in potato growing, which provides for the co-culturing of potatoes with honey crops. Phacelia tanacetifolia (PhaceliatanacetifoliaBenth) is selected as honey crop, which is a valuable green manure. It allows to reduce the need for organic and mineral fertilizers, increases the ecological cleanness of products, favors the growth of potato yield, provides the additional honey yield. Phacelia significantly improves the soil structure, displacing a significant part of weeds, providing natural loosening of the soil, protection from drying out, from pests and parasites. The co-culturing of potatoes with phacelia protects the environment from the use of dangerous plant protection products. If the economic effect is defined as the difference between the profits of innovative and traditional technologies, then, according to preliminary calculations, the level of profitability of innovative technology in potato growing is 1.9 times higher, and the profit from 1 ha is 1.6 times higher compared with the traditional technology. Large-scale development of the proposed technology is hampered by the lack of potato planters and seed planters, which provide planting of potatoes and sowing seeds of honey crops simultaneously, in the Russian market and the markets of the European Union. An innovative technology - mounted seeder for potato planters was developed by the staff members of the Pskov State University. The article describes the main agro-technological requirements to this device. A general model and a kinematic scheme were developed to visualize the combination of the working elements of the potato planter and the mounted seeder. The developed model falls into the type of seed planters, which is designed to sowing in drills the seeds of honey crops (phacelia) in the furrow between potatoes at the time of the forthcoming closing of this furrow by soil, and can be used in agricultural engineering. Potential consumers of the proposed innovative technology in potato growing and the developed mounted seeder are farm enterprises and agricultural production cooperatives, which have small plots of land, use crop rotation systems in potato growing, and work for reducing costs and increasing the yield of potato cultivation.

Improving the efficiency of using tractor-transport units (tractor trains) in the central agricultural zone of the Amur Region is an economically important issue, especially relevant for small peasant farms. This is due to the fact that in such farms the area of fields occupied for the cultivation of agricultural crops is relatively small, while most of them belong to the category of slope lands. It was also found that during the periods of sowing and harvesting operations, traffic on agricultural roads is hampered by safety conditions due to regional climatic features, which include a large amount of precipitation. In this connection, the use of vehicles for the transportation of seed, fertilizers, plant protection products and other goods, and the export of crops in these conditions seems to be a rather complicated operation. It should be borne in mind that in many, the main energy means are wheeled tractors of class 1.4, and not cars of various cross-country ability, therefore, in order to increase the efficiency of the use of available mechanization means, it is necessary to use them for the transport of goods, and as part of multi-link tractor trains in particular. At the same time, when driving on on-farm field roads with a limited width, the turn of multi-link trains is difficult due to the failure of the second and subsequent aggregated trailers to comply with the safe transport corridor, since the second trailer, when turning, shifts to the center of the road and creates an emergency situation for oncoming traffic. In order to eliminate the identified shortcomings and create safe conditions for traffic, an automatic device was developed that allows you to shift the second trailer when turning from the center to the side of the passing traffic, thereby regulating the transport corridor and not creating emergency situations for oncoming traffic. The paper presents the results of experimental studies on the use of a transport unit consisting of a class 1.4 tractor and two 2PTS-4 trailers in the production modes of multi-link tractor trains.

Global strategies, including application of chemical plant protection products, are important in the cultivation of safe corps and preservation of human health. A promising area of preventive medicine, agronomy, agroecology and agroengineering is the optimization of methods of pesticide formulations application. The aim of the work was a hygienic assessment of the most common and latest methods of crops treatment with chemical pesticides. Results. The biological effectiveness of different types of pesticides is achieved by different application rates of the working solution. The most common method of pesticide application is spraying, which ensures the application of pesticides in the drop-liquid state and is characterized by low consumption of active substance per unit area, variable-controlled distribution on the treatment surface, provides good adhesion and retention on facilities, allows the use of combined formulations. One of the most effective ways to minimize the negative impact of chemical plant protection products and achieve economic success is a rational approach to the choice of pesticide application, as it takes into account the hazard class of pesticides, the presence of water protection zones, the sensitivity of target crops, etc. Conclusion. Rational application of pesticides includes minimizing the overall effect of pesticides on human health and the environment and achieving high-targeted biological efficiency. Adherence to the methodology of choosing the type of pesticide application and selection of the type of spray is a key point in optimizing the rational use of chemical plant protection products, which requires a detailed study from the standpoint of both efficiency and safety. Control over compliance with the recommendations should be included in sanitary-hygienic and sanitary-ecological monitoring.

In the context of the intensive use of chemical plant protection products, the issue of ecologization is acute. The concept of environmental protection of grapes, as the most pesticidal crop, is based on the principles of managing the phytosanitary state of agrocenoses as a whole. At the same time, entomophages play a key role in the formation of a balanced self-regulating ecosystem. The development and application of the so-called biorational technologies with the predominant use of safe ecologically “soft” chemical plant protection products in the grape protection system is a prerequisite for activating a useful entomofauna. The targeted effect on the entomophage populations is based on phytosanitary monitoring, on their integration with pesticides. The article presents the results of many years of faunal studies of grape agrobiocenoses, reveals the most effective mechanisms for the regulation of dangerous bunching leaves and cotton scoops. Based on the original drawings, a morphological description of the most common species of tachy flies is given - Elodia tragica Mg., Pseudoperichaeta insidiosa, Tawnsendiellomyia nidicola.

Aviator Xpro EC 225 containing the active substance bixafen was assessed by VKM in spring 2013, and it was concluded that the metabolite M44 has potential for groundwater contamination. Furthermore, VKM assessed in late 2013 the relevance of this metabolite in accordance with the EU guidance document on metabolites in groundwater, and concluded that the malformations observed in rabbits exposed to the metabolite should be considered treatment related. VKM also concluded that the data presented to evaluate the possible genotoxic properties of the metabolite was insufficient to reach a conclusion. Based on this, the Norwegian Food Safety Authority rejected the approval of Aviator Xpro EC 225. The applicant has now submitted results from an in vivo study to strengthen the basis for assessment of genotoxic properties, and also submitted new historical controls in relation to the experimental studies on foetal developmental effects in rabbits. The VKM Panel on Plant Protection Products has discussed the questions raised by The Norwegian Food Safety Authority on the basis of the new data, and has the following opinion: On the assessment of genotoxic properties of the M44 metabolite of bixafen, one of the active ingredients of Aviator Xpro EC 225. It is the view of VKM Panel on Plant Protection Products that the new in vivo mouse micronucleus study, supplemented together with a separate study demonstrating bioavailability, overrides the results of the in vitro clastogenicity studies. Taken together, it is the opinion of VKM that under the conditions studied, M44 should be considered as non-genotoxic. On the assessment of the relevance of the foetal malformations in M44 exposed animals. VKMs Panel on Plant Protection products has assessed the arguments and new historical control data presented by the applicant, intended to show that metabolite M44 is not teratogenic. It is however the opinion of the Panel that the arguments and the new historical data provided by the applicant do not alter the panel’s previous conclusion; that the malformations observed in rabbits exposed to the metabolite M44 should be considered treatment related.

Annually more than 2 million tons of chemical plant protection products are introduced into the fields of the planet due to the need to preserve the crop. However, with multiple introduction of persistent pesticides, soil can become a source of pollution of crop production. The Purpose of our work was to predict the danger for children of all ages when consuming agricultural products contaminated with fungicides of the amides and triazoles classes. Materials and Methods. For an integrated assessment of the potential hazard on a four-graded scale, the allowable daily intake, the half-life in plants, and the average daily consumption of the product were estimated. When estimating the average daily consumption of products for children under the age of 18, the safety coefficients were used. Results. According to the persistence in agricultural cultures, fungicides cyflufenamide and difenoconazole were classified as hazard classes 3 (moderately stable). By the integral indicator of the danger when consuming pesticide-contaminated products for adults, difenoconazole is very dangerous (grade 4), cyflufenamide —moderately dangerous (grade 3). Conclusion. It has been established that for children, depending on their age, both studied active substances can be from extremely dangerous for infants and children of preschool age to a low or moderately dangerous for adolescents.
