pesticides
chemicals that are toxic to pests - have many types that are specific to target pest
rodenticides kill rodents fungicide kill fungi, etc
can cause pests to develop resistance w overuse
GMOs in crops
gene for pest-resistant trait is added through GMO
ex. bt corn w/ bacteria gene that produces Bt crystals toxic to pests
roundup ready crops are gm resistant to broad herbicide meaning roundup will kill weeds but not crops
gmos and genetic diversity
gm crops are genetically identical. if pest/disease affect the crop, they’re all vulnerable and there’s no chance of a genetic mutation providing an adaptive trait
roundup ready crops
have increased herbicide (glyphosate) use since crops can’t be harmed by it
bt corn has decreased insecticide use since corn makes its own insecticide
