Principles Of Integrated Pest Management And Their Applications In Field Crops: Agro-Ecological Integrated Pest Management And Pests Of Field Crops & ... Pests Of Field Crops And Their Management

<p>Cultivation of crops is actually against natural process based on ecological concept. From time immemorial human species destroyed forest and various natural ecosystem and started growing crops. Growing crops and animal husbunding is nothing but maintenance of homogeneous population. However nature try to maintain heterogenity. Hence weeds insect pests and plant diseases in any crop ecosystem are inevitable and unavoidable. without understanding this basic concept scientist all over the world doing agricultural research to curtail insect pests plant diseases and weeds. Insecticides benefit the crops; however they also impose a serious negative impact on the environment such as biodiversity erosion non-sustenance biomagnification of pesticides insect resurgence toxicity to non-target beneficial organisms pesticide residues related human health isssues etc. Green revolution encourages use of high yielding crop varieties for higher food production. However high yielding varities are input responsive and perform well only when higher amount of irrigation water fertilizers pesticides and other agricultural inputs are applied. If a crop variety requires higher inputs it also attracts pest and diseases. Due to misconception of Agro-ecology the present world have contaminated the entire earth's biosphere with toxic pestcides and agricultural chemicals.</p>
