Spraying

Spraying: Pesticides can be sprayed in the storage structure before storing food grain. This kills the pests before the arrival of stocks and also eliminates chances of contamination of food grain with pesticides.

Pesticides help farmers to produce more with less land, by increasing crop productivity by between 20 and 50 percent. In addition, pesticides allow farmers to maximize the benefits of other valuable agricultural tools, such as high quality seeds, fertilizers and water resources. Pesticides are therefore an indispensable tool for the sustainable production of high quality food and fibers.

Pesticides help keep food affordable. Farmers grow more food on the same land with the help of pesticides. Studies have shown that growers of organic vegetables spend significantly more on hand weeding compared to growers who use herbicides. This explains why organic food is more expensive than conventionally grown food.
