Recent weed management techniques in micro irrigation system: Review

Weeds are considered as one of the important biotic constraints in agro ecosystems. In many parts of the world, chemical control of weeds with herbicides is the predominant method of weed management in crops. Recently, Drip Herbigation is essential to developing a holistic system in micro irrigation for weed management. The application of herbicides through a drip irrigation system has been used successfully for the control of weeds. Because many vegetable growers already use a drip irrigation system for water management, the injection of herbicide can easily and inexpensively be achieved with the addition of an injection pump and the required safety equipment for the injection herbicides. The extent movement of herbicides applied through irrigation systems is a function of solubility, adsorption and volatility. With Herbigation, there will be efficient use of both water and herbicides. Herbigation could be included as one of the components in integrated weed management.
