Huai'an, Jiangsu Province: The hybrid rice Shenliangyou 11 we planted here is almost ready. Now that rice blast occurs seriously in the field, can we use 40% rice bran, 80 ml per mu, 25% prochloraz, 50 ml, 80%? Iilicin 20 ml spray control, whether it can control the condition, whether it will occur pancreas?
A: The text message reflects that the occurrence of rice blast disease in the field is heavy. In this field, the number of rice blast pathogens is sufficient, and rice has poor resistance to rice blast, and the field environmental conditions should be favorable to the occurrence of panicle blast, which is prone to panicle blast. Because the field rice is still in the imminent full heading stage, panicle blasts and other panicle blasts have not yet entered the disease stage, but the bacteria may have invaded the tissues of the stem, branches, glume and other parts of the ear, and should be used as soon as possible to have a therapeutic effect. The highly effective and applicable drugs prevent and cure ear blasts.
The three drugs mentioned in the text message are suitable drugs for controlling rice blast, but rice blast pathogens are resistant to drugs such as prochloraz and rice bran. If the field has a large number of rice blast resistant strains that are resistant to these drugs, applying the method described in the text message will not only make it difficult to control the condition of the leafhopper, but will also miss the timing for the prevention and treatment of panicle blast, resulting in severe panicle blast and large yields. Less. It is recommended to select early use of trifloxystrobin, azoxystrobin, and mixed sprays with kasugamycin, rice bran amide, rice bran, etc. to better control leaf blast and reduce the occurrence and damage of ear blast to a certain extent. .
