Pesticide use in the landscape has been reduced through the implementation of integrated pest management (IPM) (Holmes and Davidson, 1984, Olkowski et al., 1978; Smith and Raupp, 1986). IPM emphasizes prevention, identifying pests and their symptoms, regular surveying for pests, determining action thresholds and guidelines, and using sound management methods. Monitoring techniques such as pheromone traps, degree-day models, and ELISA kits, in addition to traditional methods, have enabled pest managers to determine accurately when to apply IPM techniques. Examples of serious California landscape insect pests successfully controlled through IPM include the ash whitefly [Siphoninus phillyreae (Halliday)], the Nantucket pine tip moth [Rhyacionia frustrana (Comstock)], and the eucalyptus longhorned borer (Phoracantha semipunctata F.).

Purpose The purpose of this paper is to analyse factors affecting the use of pesticides in intensive vegetable farming in Java, Indonesia. Evaluating such factors is expected to provide appropriate policies to reduce pesticides, and eventually, mitigates the adverse impacts of pesticides on human health and the environment. Design/methodology/approach Data were compiled from a farm survey of randomly selected 240 vegetable farmers in three regions of Java in 2014. A concept of economic threshold was employed to analyse the pesticide use determinants, which were estimated using econometric models. Findings Factors leading to the increase in the application of pesticides were the number of observed insect pests, prices of vegetables, use of local varieties, and use of mixed pesticides. Conversely, factors lowering the use of pesticides were the number of observed diseases, the cost of pesticides, and area planted to vegetables. The most important factor in influencing pesticide use was farmers’ perception on the correct prediction of yield losses associated with pests and diseases. Research limitations/implications The sample for this research is somewhat low and the analysis was based on one-year data of the quantity of pesticides in a formulation. Practical implications The use of pesticides can be reduced by training farmers on crop protection practices, which provide correct information on pests and diseases. Policies related to the price of pesticides would be ineffective, as farmers still highly relied on pesticides. These findings will be useful for reducing the use of pesticides in intensive vegetable farming in Indonesia, and in tropical countries in general. Originality/value Pesticides have two opposite properties: to increase income on the one side and to cause devastation of life on the other side. Because pesticides are generally less selectively toxic than would be desired, non-targets including humans and the environment must be protected from contamination by these agrochemicals. This study found the most important determinants for reducing pesticide exposures in Indonesian intensive farming.

Transitioning towards agroecology involves the integration of biodiversity based ecosystem services into farming systems: for example, relying on biological pest control rather than pesticides. One promising approach for pest control relies on the conservation of semi-natural habitats at the landscape scale to encourage natural enemies of insect pests. However, this approach may require coordination between farmers to manage the interdependencies between the providers and beneficiaries of this ecosystem service. The main objective of this study was to identify hindrances to landscape-scale coordination strategies to control pests. To this end, we used a theoretical framework specifically designed to explore social interdependencies linked to ecosystem services. We applied this framework to a participatory research case study on pest control in apple orchards in southwest France to identify and describe key obstacles. We found four main impediments: (1) The perception of most stakeholders that the landscape does not deliver significant pest control services, (2) the challenge of coping with agroecological uncertainties, (3) an integrated vertical supply chain focused on pesticide use, (4) the existence of independent, non-collective alternatives. We discuss the potential of overcoming these obstacles or turning them into opportunities that promote a transition to agroecology and the integration of ecosystem services in farms and their supply chains.

Abstract Pesticides are commonly used in the prevention or control of pests such as insect pests, mites, disease, and weeds in crops to increase production and productivity. The aim of the current study was designed to assess the pesticide utilization, practice, pesticide-related knowledge, and perception of farmers and to evaluate the protective measure taken by the farmers. For this purpose, field surveys were carried in Amibara, Gewane, Assayita, and Fentale districts during the 2019 main crop cropping season. A total of 128 small-scale holder farmers, 25 large-scale holder farmers, 30 sprayers, and 12 extensions were interviewed closed and opened questioners. The results revealed that the majority of farmers (44.5%) between the age of 41 and 50 years old, while only fourteen those (9.4%) were more than 51 years old. Regarding the educational level of smallholder farmers, 49.2% were illiterates, 27.9% elementary school, 17.0% secondary school and 5.8% had completed high school. The majority of sprayers (66.7%) were elementary school level. The unsafe and indiscriminate use of pesticides in agriculture represents a major hazard to the environment and human health. All farmers (100%) acknowledged that pesticides were harmful to their health and the environment. Over 63.2% of the farmers did not read or follow pesticide label instructions, and 78.5% did not use any personal protective equipment during spray operation and formulation pesticides. When disposing of pesticide empty containers, respondents adopted unsafe practices such as through near irrigated canal, burning, dumping in the field, domestic use, and burying. Less than 50% of smallholder farmers obtained training on pesticide use 14.8%, application method 16.6%, disposal of empty container 13.3%, and storage and safety 10.2%. Results also demonstrated that all farmers showed poor practices regarding the disposal of empty pesticide containers. The present study revealed that the utilization and practices of pesticides in irrigated cotton-producing areas in the Awash Valley of Ethiopia. It also demonstrated the role of retailers, importers, and state extension workers in providing information and advice to the farmers. Future researches should focus on the merit and demerit of mixing two or more pesticides to control insect pests and on the evaluation of different pesticide resistance development against a variety of insect pests in cotton-growing areas.

The study was designed to assess the extent of pesticide use and profitability of bitter gourd production at farm level in selected areas of Jashore district during January-May, 2019. Average farm size was 0.79 ha and average bitter gourd cultivated area per farmer was 0.07 ha. Most of the farmer cultivated local variety, which is called Gajkorola and some farmer cultivated hybrid korola such as Gonggajoli, Tia and BARI Korola-1 variety. About ninety-nine percent farmers sprayed insecticides and fungicides in their fields to protect crops from different insect pests and diseases. Thirty-nine percent farmers used pheromone trap for crop protection. A farmer averagely used 11.19 times spray in their fields and its range was 5-18 times in a season. The average yield of bitter gourd was 16.74 t ha-1 for non-IPM farmer and 16.16 t ha-1 for IPM farmer. The average total cost of production of bitter gourd was Tk. 203984 ha-1 for non-IPM farmer and Tk. 191246 ha-1 for IPM farmer. Gross return was Tk. 389705 ha-1 and net return was Tk. 185721 ha-1 for non-IPM farmer. While, gross return of IPM farmer was Tk. 360828 ha-1 and net return was Tk. 169582 ha-1. Benefit cost ratio was 1.91 and 1.89 for non-IPM and IPM farmer, respectively that means bitter gourd production was profitable. Cent percent farmer reported that IPM technology was time-consuming method and it was not only the measures to protect pests. Int. J. Agril. Res. Innov. Tech. 10(2): 110-115, December 2020

Background. Population growth has led to the need to increase global food production. Pesticides are an important tool used in efforts to control insect pests. About 20–30% of agricultural produce is lost annually due to insect pests, diseases, weeds and rodents. While pesticides are effective against pest populations, if used injudiciously, they may pose health hazards to humans, domestic animals, natural enemies of crop pests and other forms of life through unwanted contamination of food, feed, water bodies and the environment. Objectives. The aim of the present study was to examine farmers' level of knowledge and awareness of environmental pollution due to unsafe use of pesticides for controlling rice pests and to explore ways of reducing their usage. Methods. The research population consisted of 120 rice farmers: 40 farmers randomly selected from each of the three rice growing districts of Bangladesh; Mymensingh, Tangail and Jamalpur. Data was collected through group discussions, direct observations and personal interviews during March 2013 to May 2014. Results. Farmers mainly sought advice on pesticide use from pesticide dealers or retailers and a very few farmers contacted government extension workers for this purpose. Most of the farmers had an understanding of natural enemies of rice pests and that the application of synthetic insecticides in the field can reduce their population. A few farmers followed integrated pest management (IPM) practices with little understanding of the adverse effects of insecticides on the environment and ecosystem. The majority of farmers understood the harmful effects of pesticides on health of human and animals, beneficial species, fish, insect resistance, soil and food. It was also found that education on pest management, information through television, more contact with extension personnel and farmers' awareness of IPM were critical factors for improving rice farmers' understanding of the ecological hazards caused by overuse of pesticides. Most of the farmers suggested that timely removal of weeds, appropriate timing for pesticide application, balanced doses of fertilizers, pest monitoring, correct dose of appropriate pesticides, pest tolerant varieties, increasing technical knowledge and skills and creating social awareness of environmental pollution among farmers were necessary to reduce the quantity of pesticides and minimize environmental hazards. Conclusions. The present study identified a need to intensify farmers' awareness and knowledge of integrated pest management and environmental pollution through extension organizations which could help promote sustainable agricultural development and improve the currently endangered bio-diversity of Bangladesh. Participant Consent. Obtained Ethical Approval. This study was approved by the PhD Supervisory Committee assigned by the Department of Entomology of Bangladesh Agricultural University.

The use (and abuse) of pesticides has increased to combat insect-pests and diseases. However, the major causes concern of are the undesirable side effects of these chemicals on biodiversity, environment, food quality and human health .Climate change will have important implications for insect conservation and pest status. Climate and weather can substantially influence the development and distribution of insects. Most of the warming over the last 50 years is likely to have been due to man-made activities. Anthropogenically induced climatic change arising from increasing levels of atmospheric greenhouse gases would, therefore, be likely to have a significant effect on agricultural insect pests. Current best estimates of changes in climate indicate an increase in global mean annual temperatures of 1[o] C by 2025 and 3[o]C by the end of the next century. Such increases in temperature have a number of implications for temperature-dependent insect pests. The Assessment investigates the relationship between pesticide use and climate for crops that require relatively large amounts of pesticide. This paper describes such input-driven agriculture, the problem of pests and diseases and the unsustainable agricultural practices that it leads to, and the socio-economic and health externalities resulting in farmer's distress in pesticide hot spots. To protect ourselves, our economy, and our land from the adverse effects of climate change, we must ultimately dramatically reduce emissions of carbon dioxide and other greenhouse gases. The causes of anthropogenic climate change are broad and often difficult to address. There is no single solution to this complex problem, but numerous opportunities exist for reducing problems of climate change. The issue of climate change is one of the most profound challenges of our time, and we believe it is a challenge that can be met. The Journal of AGRICULTURE AND ENVIRONMENT Vol. 8, 2007, pp. 83-91
