tailieunhanh - A review on different weed management approaches

It was examined that weeds cause a lot of problems in the crop field. Weeds compete with the main crop for nutrients, water, food, space, sunlight etc. Weeds utilize the nutrients provided to the main crop and sometimes dominate the main crop. Some weeds are very noxious and they are harmful for both humans as well as animals. It is clearly revealed from studies done in field of weeds that use of herbicides used to control weeds cause many effects on soil as it leads to degradation in the quality of soil, water as well as it pollutes environment. And also repeated use of same herbicide makes the weeds resistant to that herbicide. Many ways used to control weeds like Mechanical control, Cultural control, Chemical control and Biological control. But now a days chemical control is too much widespread in which use of different herbicides done. Overuse of chemical fertilizers harms soil health as well as decrease quality of environment. So a new approach called Integrated Weed Management (IWM) came into light in which all the approaches are combinely used just to reduce the alone use of herbicides. | EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 8 Number 08 2019 Journal homepage http Review Article https A Review on Different Weed Management Approaches Harmanpreet Kaur1 Gursharnpreet Singh Brar1 and Poonam Pandurang Shete2 department of Agronomy School of Agriculture Lovely Professional University Phagwara Punjab India department of Plant P Lovely Professional University Phagwara Punjab India Corresponding author ABSTRACT Keywords Environment Fertilizer Integrated Weed etc. Article Info Accepted 22 July 2019 Available Online 10 August 2019 It was examined that weeds cause a lot of problems in the crop field.

Introduction Weeds have been known since the ancient times. Weeds may be defined as plants other than crop plant or any unwanted plant grown in the main field with crop plants. Weeds not only grow with the main crop but also .
