The Role of Allelopathy in Pest Management and Crop Production – A Review

Abstract

Allelopathy may be a current ecological advance of interference between organisms that will use for handling unwanted plants, insect pests, and diseases in plants. In many crops, allelopathy are often used resulting crop rotation, victimization cover crops, mulching, crop dyspnoeal and plant extracts for ordinary insect pest management. Plant pathogens together with fungi, bacteria, viruses, and nematodes are responsible for great yield losses in several economically vital crops. Use of artificial agrochemicals as soil covering, foliar spray or seed dressing is that the preferred approach for the management of crop diseases in recent days. However, due to the adverse effects of those chemicals on health and environment, customers are presently tightened turn out, that is freed from these chemicals. Natural compounds derived from plants are a lot of environmentally safe than artificial chemicals. Several recent studies have shown that allelochemicals will effectively be used for the management of various plant pathogens. Allelopathy so offers a lovely environmentally friendly different to pesticides in agricultural pest management. Their biopotency is often increased by structural changes or the synthesis of chemical analogs supported them. Though the progress during this regard is slow, even so some promising results are returning and a lot of are expected within the future. This review makes an attempt to discuss these characteristics of allelopathy for the justifiable management of pests.
