Influence of pre-emergence and post-emergence of herbicide on weed parameters, growth and yield attributes of blackgram: A review

Abstract

Blackgram (Vigna mungo L.) is one of the important pulse crops grown in India under wide range of agro-climate zones which belong to the family “Leguminoseae”. It can be cultivated in all the seasons, but most of the area is in Kharif cultivation with irrigated condition. The importance of weed control measure in blackgram is emphasized by the fact that weeds alone cause more damage to crop than all pests and diseases. Therefore it is essential to maintain weed free condition to attain higher economic yield. With the changing scenario of weed control practices, farmers are looking for broad spectrum post emergence herbicides to control sedges, narrow leaved and broad leaved weeds at later stage. Review of various literatures revealed that it is very important for enhancing the weed efficiency by application of suitable pre and post emergence herbicides and other methods for effective control of diversified weed flora in blackgram.
