Crop cultivation is actually against nature, as per ecological theory and concepts. While cultivating crops, farmers maintin homogenous plant population. As per ecological theory and principles, an unit area having homogenous population tends to be converted automatically into heterogenous by nature. For that reason, weeds are flourshing when ever crops are been grown. Also various biotic factors like insects and disease causing organisms follows, as the crop
Crop cultivation is actually against nature, as per ecological theory and concepts. While cultivating crops, farmers maintin homogenous plant population. As per ecological theory and principles, an unit area having homogenous population tends to be converted automatically into heterogenous by nature. For that reason, weeds are flourshing when ever crops are been grown. Also various biotic factors like insects and disease causing organisms follows, as the crop growth proceed further. Pest management in cultivable crops is challenging in the present scenario due to intensive and extensive cultivation practice. To meet out the needs of ever growing human popluation, we are forced to extend the area of cultivation as well as many crops per year. Sustainable pests mangement on crop plants is gaining momentum. Pesticide residue free food produces like grains, vegetables, fruits, spices and medicinal plant products are in demand around the world. Hence, sustainable crop cultivation with respect to pest management using Integrated approach is the best solution. Latest techniques and novel insecticides plays a major role in sustainable pest management.
Various technologies were derived from sub branches of Entomology viz, agricultural entomology, medical entomology, forest entomology and veterinary entomology for the effective control/management of insect pest fauna. Fundamental knowledge with respect to insect morphology, anatomy and physiology is essential for proper management of deleterious insects. The science of insects is a dynamic field, which require periodical updation. Hence, knowledge on basic sc
Various technologies were derived from sub branches of Entomology viz, agricultural entomology, medical entomology, forest entomology and veterinary entomology for the effective control/management of insect pest fauna. Fundamental knowledge with respect to insect morphology, anatomy and physiology is essential for proper management of deleterious insects. The science of insects is a dynamic field, which require periodical updation. Hence, knowledge on basic science viz., insect morphology, anatomy, physiology and taxonomy is essential for deciphering research on applied scientific principles like Integrated Pests Management, vector control and their diseases.
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 c
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.
