Resumen
Objective: to reflect briefly on the importance of the use of agrochemicals in the productivity of some crops according to their contribution to yield, and some implications of their agricultural consumption.
Design/methodology/approach: based on related literature and some experiences in the field on the use and consumption of pesticides.
Results: pesticides are synthetic, microbial, or derived organic compounds used in plant growth programs to prevent or control pests, diseases, and weeds. Also, mineral nutrition (with macro and micronutrients) is considered as agrochemicals. However, the effects on the contamination of soils, groundwater, lakes, seas, and oceans due to its use is increasing. Mexico is a large consumer of fungicides, insecticides, fertilizers, and herbicides for agricultural uses.
Limitations on study/implications: unmeasured use of any type of pesticide can produce tons of pesticide-trash. Some traces of active or inert ingredients can be detected in bodies of water.
Findings/conclusions: the constant risk of agronomic yield losses can be substantial without the use of agrochemicals. Without the application of pesticides, yield losses can reach 100%.
