Causes and control methods of white ears of wheat

Now is the harvesting stage of new wheat, and the phenomenon of white ears of wheat may be caused by a variety of factors, including pests and diseases, climatic conditions, insufficient soil nutrition or improper planting management measures. This may result in a loss in wheat yield and quality. Let’s learn together about the causes and prevention methods of white ears of wheat.

1. Pest and disease control

Pests and diseases such as wheat fusarium rust, stem base rot, sheath blight, take-all disease and wheat stem fly can cause white ears of wheat.

Prevention and control measures: During the wheat filling period, the "one spray and three preventions" strategy is adopted, using fungicides such as fenpropimorph, triadimefon, and diniconazole, as well as insecticides such as thiamethoxam, imidacloprid, and carboplatin for prevention and control.

2. Issues of returning straw to fields

Improper straw return to the field may lead to an imbalance in the carbon-nitrogen ratio in the soil, affecting wheat's absorption of nitrogen and resulting in white ears.

Prevention and control measures: Spray nitrogen-containing foliar fertilizer , supplement medium and trace elements, and pay attention to the quality of future straw return to the field.

3. Influence of dry hot wind

Dry and hot winds can cause water imbalance in the wheat body, hinder photosynthesis, and cause white ears.

Prevention and control measures: Select drought-resistant and heat-resistant wheat varieties, strengthen late-stage field management, irrigate reasonably, spray potassium dihydrogen phosphate or full-nutrient foliar fertilizer to enhance wheat's stress resistance.

4. Other factors

Variety problems, land conditions (such as saline-alkali land ), and human factors (improper farming operations) may also cause white ears.

Prevention and control measures: Select suitable varieties, improve soil conditions, and standardize agricultural operations.

In short, in the middle and late stages of wheat growth, especially when the temperature rises sharply, farmers should go to the fields to check in time so as to discover and take measures as early as possible to reduce the possibility of white ears. Once white spike appears, it is difficult to fully recover, so prevention and early intervention are crucial. Through the above-mentioned prevention and control measures, the phenomenon of white ears of wheat can be effectively reduced and the yield and quality of wheat can be guaranteed.
