Abstract

Plant disease control is mainly based on extraneous application of pesticides to improve agriculture productivity. However, only a part of applied pesticides is used for killing of pathogens and pests. Large part of applied pesticides remains either as residual pesticide or gets volatilized or leached resulting in ecological and environmental problems, and human health hazards. The increased consumer demands for safe food have invigorated research on development of safe and ecofriendly biopesticides. The use of microorganisms for biological control of pests is considered as a pragmatic approach which can drastically lessen the adverse outcomes of agrochemicals in soil. Rhizospheric microorganisms isolated from various crops produce different antagnostic compounds and inhibit the growth of various phytopathogens and insect pests. Moreover, in several plants, hormones like salicylic acid, jasmonic acid and ethylene contribute towards induction of both, systemic acquired as well as induced systemic resitance. In this article, antagonistic rhizosphere microorganisms have been explored for control of phytopathogens. Further, recent advances in field of biopesticides using rhizosphere microorganisms under field conditions is discussed for improvingcrop productivity in sustainable agriculture
生物防治剂在植物病害防治中提高食品安全的潜力
植物病害防治主要是通过外用农药来提高农业生产力。然而,使用的农药中只有一部分用于杀灭病原体和害虫。施用的农药有很大一部分以残留形式存在,或挥发、浸出,造成生态环境问题,危害人体健康。消费者对安全食品需求的增加,促进了安全环保生物农药的研究开发。利用微生物对害虫进行生物防治被认为是一种实用的方法,可以大大减少农用化学品对土壤的不良影响。从不同作物中分离出的根际微生物产生不同的拮抗化合物,抑制各种植物病原体和害虫的生长。此外,在一些植物中,水杨酸、茉莉酸和乙烯等激素有助于诱导系统获得性和诱导系统抗性。本文探讨了拮抗根际微生物对植物病原菌的控制作用。此外,还讨论了在田间条件下利用根际微生物进行生物农药的研究进展,以期在可持续农业中提高作物生产力
