CHAPTER 8 PESTICIDE A SUBSTANCE USED TO MANAGE PESTS INSECTICIDES-PESTS HERBISIDES-PLANTS FUNGICIDES-FUNGI PESTICIDES INORGANIC COME FROM MINERALS-BORON,COPPER,SULFUR NATURALLY DERIVED ORGANIC PESTICIDES COME DIRECTLY FROM THE PLANTS OR MICROORGANISMS SYNTHETIC ORGANIC MAN-MADE FROM ORGANICS MICROBIAL INCLUDE BACTERIA,FUNGI,NEMATODES AND VIRUSES PESTICIDES BY ACTIVITY-TIMING 1)
PROTECTANTS APPLIED TO PREVENT INJURY
2) CONTACT POISONS BY CONTACT 3) SOMACH POISONS EATEN 4) SYSTEMICS ABSORBED BY PLANT KILLS PEST IF IT INGESTS PLANT 5) TRANSLOCATED HERBICIDES ABSORBED BY PLANT AND DESTROYS WEED 6) NONSELECTIVE PESTICIDES AFFECT A WIDE RANGE OF ORGANISMS
