What to Do About Corn Stalk Rot? Detailed Control Methods
What is corn barren stalk disease? An introduction to the symptoms of corn barren stalk disease: corn usually produces 1-2 ears, most commonly one ear, but during production, barren stalks often appear, affecting yield increases. For example, surveys in Kuandian, Yanyan, Benxi, Huanren and other places in Liaoning found barren stalk rates of 12%-20%, with a yield reduction of 50kg per 667 sq m...
What should be done if corn stalk rot occurs? How should it be controlled?Control methods for corn stalk rot:
1. Choose disease-resistant varieties. In production, attention should be paid to eliminating susceptible varieties and selecting varieties with strong resistance.
2. Chemical control. In the early stage of the disease, chemical control can be chosen, with the first choice being a 300-fold dilution of 58% metalaxyl·mancozeb, mixed with a 500-fold dilution of 50% carbendazim, or a 1500-fold dilution of Bingchukang No. 2, or a 3000-fold dilution of Bingchukang No. 3 and other fungicides, sprayed 2 times (it also has a good effect on "corn crazy top disease"). To simultaneously control pests such as corn borer and cotton bollworm and promote corn yield increases, it can be mixed with insecticides such as a 1500-fold dilution of 25% Yisaoguang and nutrient regulators such as 0.1% "Sanheyishnegchan su" and sprayed together.
3. Prune diseased leaves. For severely diseased plants whose corn whorl leaves have already twisted and rotted, scissors can be used to cut off the leaves wrapping above the tassel, so as to facilitate the normal emergence of the tassel, and the cut diseased leaves should be taken out of the field and buried deeply.
