How to Manage Weed in Moong Crop?

26/03/2020Posted on

Weed management is a very important activity in moong crop. If not managed properly, it can significantly reduce the production of the yield. These weeds compete for the nutrients, moisture, light, location etc. with the main crop and decrease its growth, yield and quality. The damage caused by weeds is more than the loss due to any other reasons like insects, pests, diseases, disease etc. The most important thing about weed management is to control the weeds at the right time. Weeds could be prevented in the following ways-

preventive method – This method includes all those activities which can prevent the entry of weeds in the field. These activities include the use of approved seeds, use of good rotten dung and compost manure, cleaning of irrigation drains, and proper cleaning of the instruments used for sowing.

Mechanical method – It is a simple and effective method for controlling weeds. It is necessary to keep the crop free from weeds between 15th to 45th day after sowing. Generally, weed management becomes more effective by doing hand weeding twice, first between 15-20 days and then within 30-35 days. However, this method requires more precautions otherwise, the roots of the plant may get damaged significantly. It also demands a lot of time and labour. 

Chemical method- Weeds can also be controlled successfully through weedicides. This method saves a lot of time and also reduces the per hectare cost. But awareness is required when using these chemicals. These weeds should be used only after knowing the appropriate quantity of weed, its time, its type, the crop etc. Use 700 ml of weedicide such as pendimethalin (Stomp Extra) by mixing it in 200 litres of clean water for each acre of the farm. It should be used within 72 hours of sowing. In the standing mung bean crop, when the weeds with narrow leaves are in their 2–4th leaf stage, then use 300 ml of Cuzalophope ethyl 5 EC (Taraga Super) or Propagusalophope 10 EC (Agile) with 200 litres of clean water for each acre of the farm.
