Pesticides are chemical preparations used to kill fungal or animal pests. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species because they are sprayed across entire agricultural fields rather than target specifics. Pesticides cover a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others. All these pesticides contributed greatly to pest control and agricultural output. Ideally a pesticide must be lethal to target pests, but not to target non-target species including man. Unfortunately, this is not the case, so the controversy of use and abuse of pesticides has surfaced. The rampant use of these chemicals has played havoc with human and other life forms. This session discusses more about the latest developments in pesticides and its effects having impact on agriculture, horticulture, floriculture, entomology and on human beings.
