Question

why should Prevention majors and biological control method be prepared for protecting crops ?

Answer 1

(such as diseases, weeds and insects) and abiotic factors (such as drought and salinity). Biotic and abiotic factors can cause huge losses of food grains and need proper treatment to control them. So it is better to take preventive measures and avoid loss in crop plant production.

Using chemical control methods is not advisable since their use creates problems. They are poisonous to plant and animal species and cause environmental pollution. They reach human beings through the food chain. On the other hand, biological control methods are safe for plants, animals, humans and the environment in general.

 

Hence, preventive measures & biological control methods are preferred for protecting crops.

Hope this helped!!!
