The pesticides:
large fields of crops (all the same) = monoculture = pests
Pests will use the crop as there food source which will reduce productivity of farming = loss of food and finance
1. use pesticides- chemicals - designed to kill the pest
PROS : chemicals = easy to obtain
easy to apply
very effective
CONS : many of them are toxic (will kill other things/ maybe humans)
Bio accumilation
Mutation in the pest leads to resistance therefore more pesticide is needed and it will be more toxic or may not work
