Answer:

Herbicides and insecticides appeared to be the most frequently used pesticides for both crops. Amino phosphonates (mostly glyphosate) represented the most used herbicides (45 % for rice up to 89 % for vegetables). Pyrethroids appeared to be the most used insecticides (accounting for 90 % of all the insecticide use reported). Approximately 75 % of respondents had not been to school and do not understand product labels. Only about 45 % of farmers respect the recommended pesticide dosage and about 10–15 % of pesticides used for rice and vegetable, respectively, are not recommended for these crops. As per WHO criteria, the mosquito local populations from the two localities were resistant to three of the four insecticides tested, as mortalities were less than 35 % for deltamethrin, DDT and bendiocarb. Higher susceptibility was observed for malathion, although the population was considered resistant in Dabou (80 % mortality) and susceptible in Tiassalé (98 % mortality). With the exception of glyphosate, residues from each of six chemicals tested for were detected in each of the sites visited in the two localities.

From the map that we have here the use of pesticides have different effect on the change in rice production in different regions of the world.

In the area that is marked black in the map, the use of pesticide led to a raise in the tons of rice produced from 1.0 to 1.6 tons.

In the area that is grey, the use of pesticide led to an increase in the tons of rice produce from 0.5 tons to 1.0 tons. Same increase can be observed in the area that is under the grey area.

While in the white area, there was no change that was noticed in the yield of rice when pesticides where used.
