Timely and high-quality application of pesticides contributes to environmental protection, economical production and production of healthy food. The efficacy of pesticide application depends not only on the quality of pesticides but also the quality of the application. One of the factor that most influences the quality of applications, from the standpoint of mechanization, are nozzles. They working liquid applied on the surface the plant resulting in the same volume of pesticide is applied to the entire surface of the plants. To achieve this goal, nozzles must be performed uniform application of working liquid per unit area, or tractor sprayer working width. The variable factor in the application of pesticides may be nozzle and operating pressure. With increasing working pressure obtained smaller droplets. The paper presents test of three different nozzles. Each nozzle is characterized by a flat jet with an angle of 110° and a flow rate of 1.6 l∙min−1 at a pressure of 3 bar. Differ from each other are by the way of disintegration of the jet. Exactly this characteristic causes that with pressure change coming to changes in the uniformity of nozzles transverse distribution. So the best distribution has nozzle with a flat jet. The coefficient of variation is between roughly from 4 to 6 % at the pressure application of 2 to 4 bar. Obtained mathematical model that describes changes in the coefficient of variation depending on pressure applications can be a good basis for easy harmonization parameters in the pesticide application.

The water sensitive paper is commonly used in the uniformity and distribution ratings of the spray droplets pattern; however, this technology still has a high cost. In this way, the present work had as objective to evaluate the quality of deposition of spray drops in different types of papers sensitive to water. The test was carried out in a wind tunnel built inside the multi-sport gymnasium of the State University of West Paraná-campus of Cascavel-PR. A semi-automated nozzle transition prototype was used to perform the tests. The variables evaluated were number of diameters, dispersion, volumetric medium diameter (VMD), droplet density, cover and droplet volume. The treatments consisted of four different types of paper compared to the water sensitive paper (control), and two nozzles. Cardboard paper stood out among the others at the cost of approximately 1% of a water-sensitive paper slip. The water sensitive paper used in agriculture can be replaced by alternative papers more economically viable and easily found in the market.

Pineapple is one of the most economically important fruit crops of Mauritius and is often sold after being minimally processed (MP). Unfortunately, minimally processed whole (MPW) and fresh-cut (MPC) pineapples are susceptible to microbial contamination that can compromise the quality of the products. It is therefore important that MP pineapples have optimal freshness, nutritional quality, and are free from microbial contamination which would otherwise constitute a public health hazard to the consumers.The main aim of this study was to assess the microbiological, nutritional, and physicochemical quality of MP pineapples sourced from wet markets and supermarkets. Samples of MPW and MPC pineapples collected from open markets and supermarkets were subjected to microbiological, pH, and vitamin C analyses. The MP pineapples were also challenged using the specific spoilage organism (SSO), Pseudomonas fluorescens and subsequently stored at either ambient or refrigeration temperature to simulate storage conditions of wet markets and supermarkets, respectively. Laboratory analyses revealed that the Total Viable Counts (TVC), pH, and vitamin C content for MPW and MPC pineapples sampled ranged from 4.8 – 5.5 Log CFU/g, 4.16 – 4.96, and 21.60 – 28.90 mg/100 g, respectively. Since the population density of TVC was less than 7 Log CFU/g, which usually marks the onset of microbiological spoilage, the products were considered to be of a satisfactory microbiological quality. Moreover, there was no statistically significant difference in the microbiological load, pH, and vitamin C content for pineapples sourced from markets and supermarkets. Taken together, this study reveals that MP pineapples sold in wet markets and supermarkets have a satisfactory microbiological, nutritional, and sensorial quality with a shelf-life of >7 hours and >5 days when stored at room (29°C) and refrigeration (4°C) temperatures, respectively.

Pesticides have been widely adopted in the farming industry to control weeds, pests, and diseases in order to minimize yield losses and maintain the quality of lowland rice products; however, farmers often over-apply pesticides. This study analyzed key factors that affected the decision of lowland rice farmers in adopting pesticides and the frequency of pesticide application. A double-hurdle model was used to estimate the factors that affected the decisions of farmers to adopt pesticides and determine the frequency of pesticide application. These results demonstrate that the adoption of pesticides was high (86%) at lowland rice farms in the study area. Lowland rice farmers were found to apply pesticides an average of eight times. Gender, age, education level, access to extension, farming experience, and access to credit significantly affected the decisions of farmers to adopt pesticides in controlling weeds, pests, and diseases at lowland rice farms. The independent variable also significantly affected the frequency of pesticide application. Towards the goal, government and non-government organizations had to increase human resources through education, agricultural extension services to young farmers had to be improved. Specifically, extension material was provided on environmentally-friendly methods of controlling weeds, pests, and diseases and other alternatives to reduce the use of pesticides at lowland rice farms.

The quality indicators are suitable tools to determine the state of the soil and the effects of different uses and management on it. The aim of the present work was to evaluate the quality of sub-tropical Argiudolls and Hapludolls subjected to different uses in Formosa, using a minimum set of indicators (MSI). Changes in soil use and the application of management techniques to maximize agricultural production are frequent in the world. In Formosa, Argentina, improvements in the productive infrastructure and low market value of the land, promote that these changes occur faster than the monitoring of the ones. The effects of 25 years of continuous agricultural use, extensive livestock in implanted pastures and fruit crops, in relation to the native forest were analyzed. The MSI consisted of five variables: total organic carbon, particulate organic carbon, total nitrogen, structural stability and bulk density. The baseline of the indicators was determined and threshold values were established. The standardized MSI was analyzed graphically. Particulate carbon and structural stability were the most sensitive indicators. Continuous agriculture degraded the edaphic system, resulting in lower values of indicators than the thresholds. It produced a decrease of 74% of the particulate organic carbon and 63% of structural stability, with possible impact on the resilience of the system. Fruit crops led to a decrease in soil quality causing particulate organic carbon and structural stability to approach values that compromise their natural recovery. The implanted pasture improved the quality of the soil with respect to the degraded native forest.
