Comment on five major IPM strategies.
Five major IPM strategies are -
1 –– Avoid use of disruptive pesticides
Food drives these systems, when you kill pests, you are killing the food or host of beneficial insects. Even seemingly safe pesticides may kill fungi on leaves that is a secondary food for some beneficials. Spray only if there is a pest problem! Repeated use of all classes of chemical poisons on your farm results in pest resistance to the poisons. The natural enemies of pests are also killed, or are starved away from the fields, and, therefore, do not have an equal chance to develop resistance as do the pests. Predators and parasites do not leave completely, but their numbers are significantly reduced compared to pest numbers. It sometimes takes several generations of beneficials to grow back the natural balance.
Certain dosages of conventional pesticides and insecticidal soaps and oils selectively kill pests and are less disruptive to biological controls. Our beneficials are compatible with "soft pesticides" like microbial insecticides, sterile male releases and pheromone mating disruption. The use of pyrethroids and broad spectrum pesticides is recommended only in extreme cases, as these kill many beneficials as well as pests.
2 –– Build beneficial refuges
Strip or trap cover crops that are never sprayed
