First I proposed an index to measure the productive efficiency of pesticide use, cost / benefit, which refers to the amount of pesticide use to produce a certain amount of crop in a year. Theoretical relationship between crop yield and cost / benefit of pesticide use is a model with the sigmoid curve: y = a + b / (1 + e^(c-rx)), where y is crop yield, x is cost / benefit of pesticide use. The results showed that global cost / benefit of pesticide use (total) increased with time during 1990 to 2007, and declined since 2007. Pesticide use (total) (kg / ha) had the similar trend. Global insecticides, herbicides, and fungicides & bactericides use and cost / benefit declined with time since 2007. During 2010 and 2014, mean pesticide cost / benefit was 0.645 g pesticide use (total) / kg crop production, and mean annual pesticide use (total) was 2.784 kg /ha. Mean cost / benefit of insecticides, herbicides and fungicides & bactericides use between 2010 and 2014 were 0.051, 0.16 and 0.074 g / kg crop production, respectively, and mean annual use of insecticides, herbicides and fungicides & bactericides were 0.221, 0.69 and 0.32 kg / ha, respectively. Globally, the cost / benefit of dithiocarbamates, bipiridils, carbamates insecticides, and organo-phosphates, and the use of dithiocarbamates, bipiridils, and carbamates insecticides have significantly declined since 2007, and conversely, the cost / benefit of triazoles / diazoles and the use of triazoles / diazoles, plant growth regulators, and amides, have significantly increased since 2007. Of the major countries, the averaged annual cost / benefit of pesticide use (total) of Brazil...

Economic Impact Of Pesticides Application On Farms To Improve Agricultural Output: A Critical Review

The paper lucidly reviewed the concept of pesticides, historical perspective of pesticides and its classification of pesticides. However, it also critically examined the economic benefits of using pesticides on crop farms and unveiled the effects of pesticides on man and the environment. The review succinctly elucidated the precautionary measures for pesticides application and safety practices to employ when applying pesticides to both field crops and stored products for maximum economic benefit
