At present, the rice dam area in our district has been in the same line, and the middle and high mountain and late-maturing rice are in the stage of breaking to the heading stage. However, the rice-necked rice blast is the biggest threat at present. Therefore, the agricultural service centers of the townships and sub-district offices in Xijiao should strengthen publicity, mobilize the masses, and guide farmers to choose pesticides on the road to ensure the increase of rice production this year.
I. Prevention and control key
In the rice blast disease-prone area, the two-line rice and other susceptible varieties, the leaf-to-be-heavy field, the partial application of nitrogen fertilizer field, and the first-type seedling block are the key points for prevention and control. Once the drug is controlled once, it can effectively prevent the neck and neck.
Second, the prevention and control method
1. Use 75% tricycloazole wettable powder 20-30 g or 100 billion live spores/gram Bacillus subtilis 10 g.
2. Mu with 30% rice glutinous rice 150 ml or 40% Fuji No. 100 ml.
The compound formulation tricyclazole is disabled to avoid affecting the control effect.
One of the above agents may be a conventional spray of 45-60 kg of water or a 10 kg motorized spray of water.
