How to treat the dry pointed yellow leaves of wheat

Wheat may encounter dry tip yellow leaves during the growth period, so how should wheat dry tip yellow leaves be treated? In fact, there are different treatments for dried wheat tips and yellow leaves caused by different causes:

Red spiders and root rot, total erosion disease, sheath blight and so on can cause dry tip yellow leaves of wheat. Wheat dry tip yellow leaves caused by diseases and insect pests can be prevented by spraying rooting agent + Metalaxyl + brassin + foliar fertilizer, which can be sprayed once every 5-7 days.

2. Lack of fertilizer and drought

If the soil fertility in the field is not enough, a large number of nutrient elements such as nitrogen fertilizer, potassium fertilizer, or lack of trace elements such as calcium, molybdenum, copper and zinc will cause wheat to turn yellow and dry tip. At the same time, drought can also cause dry, pointed and yellow leaves of wheat. Fertilizing and watering should be carried out according to the actual situation.
