Phalaris minor and wild oat weeds are two common types of weeds that can be seen growing in wheat crops. These weeds are known to compete with the crop for nutrients and water, resulting in reduced yields. Therefore, farmers must take preventive measures to control and eliminate these weeds from their fields. Here’s some information on the control of phalaris minor and wild oat weeds in wheat (kanak) crop.
Phalaris minor Control:
Phalaris minor or ‘canary grass’ is a widespread weed that often grows in wheat fields. Here are some ways to control it:
• Crop Rotation: One effective way to control phalaris minor is crop rotation. Farmers should grow non-host crops such as cotton, peas, or mustard in between wheat crops. This will help in the eradication of weed and reduce their build-up in the soil.
• Herbicides: There are several herbicides that can be used to eliminate phalaris minor. These include Isoproturon, Clodinafop, Flupropanate, and Fenoxaprop. These herbicides should be applied during the early stages of weed growth for best results.
• Physical control: Physical control measures such as hand weeding, hoeing, and tilling can also be used to control phalaris minor in wheat fields. These methods are suitable for small-scale farms.
Wild Oat Control:
Wild oat, commonly known as “Jangli Jai”, is also a common weed found in wheat fields. Here are some ways to control it:
• Crop rotation: crop rotation is an effective way to control wild oat. The farmers should avoid consecutive planting of wheat or other host crops that promote the growth of wild oat, such as barley.
• Use of herbicides: Herbicides such as Clethodim, Fenoxaprop, Tralkoxydim are effective against wild oat. It should be applied during the early stages of weed growth.
• Mechanical control: This includes hand-weeding and mowing. These methods are effective in small scale farming but are time-consuming and labor-intensive.
In conclusion, phalaris minor and wild oat are two common weeds found in wheat crops that require immediate attention. Farmers must use a combination of physical, cultural, and chemical control measures to effectively manage these weeds. Crop rotation, herbicides, and physical control methods are the most effective ways to control these weeds and ensure optimal crop yields.
