BACKGROUND Accurate pesticide use data are essential when studying the environmental and public health impacts of pesticide use. Since the mid-1990s, significant changes have occurred in when and how glyphosate herbicides are applied, and there has been a dramatic increase in the total volume applied. METHODS Data on glyphosate applications were collected from multiple sources and integrated ...
was estimated to be around Rs. 22 billion (USD 0.5 billion), which is about 2% of the total world market. The pattern of pesticide usage in India is different from that for the world in general. As can be seen in Figure 1, in India 76% of the pesticide used is insecticide, as against 44% globally (Mathur, 1999). The use of herbicides and fungicides is correspondingly less heavy. The main use of...

The primary focus of the study is the changes that occurred in the pesticide-use structure of cotton production sector of India, owing to the diffusion of Bacillus thuringiensis (Bt) technology. Studies from different countries show that transgenic Bt crops can reduce chemical pesticide use with positive economic, environmental, and health effects. However, most of these studies build on cross-...
BACKGROUND This paper discusses U.S. agricultural pesticide use trends from 1964 to 2010 based on estimates developed from USDA surveys, and the influence of economic factors, agricultural policy, and pesticide regulation on aggregate quantities and mix of pesticides used. RESULTS Synthetic organic pesticide use grew dramatically from the 1960s to the early 1980s, as farmers treated more and ...
Integrated Pest Management (IPM) is a leading complement and alternative to synthetic pesticides and a form of sustainable intensification with particular importance for tropical smallholders. Global pesticide use has grown over the past 20 years to 3.5 billion kg/year, amounting to a global market worth $45 billion. The external costs of pesticides are $4-$19 (€3-15) per kg of active ingredien...
To inform current and future pesticide availability to glasshouse vegetable growers, the current project trialled more than twenty products, including existing industry standards, against four key pests of glasshouse tomatoes and bell peppers. These included experimental conventional chemical pesticides as well as alternative biopesticide and biorational products based on phytochemicals, microb...
Imidacloprid is a widely used pesticide in agriculture for controlling sucking insect pests, as a seed dressing, for soil treatment and as a foliar treatment in a variety of crops and orchards. Imidacloprid undergoes extensive metabolism in plants and forms monohydroxy imidacloprid, imidacloprid guanidine, imidacloprid olefin and a monoglucoside of 6-chloropicolyl alcohol. The majority of toxic...
Understanding farmers’ perception is important in the development of sustainable and cost-effective integrated pest management strategies. Hence, farmers’ perception on rice insect pests and pesticide use was evaluated by selected 112 farmers composed of 77% males and 23% females, over the rice growing areas of North Cotabato, Central Mindanao, Philippines. 62% of farmers that were interviewed ...
A convenience survey of 702 certified pesticide applicators was conducted in three states to assess the use of 16 types of engineering controls and 13 types of personal protective equipment (PPE). Results showed that 8 out of 16 engineering devices were adopted by more than 50% of the respondents. The type of crop, size of agricultural operation, and the type of pesticide application equipment ...
