How can rice white-tip nematode disease be controlled effectively?
After the Beginning of Spring, some areas in the south begin preparing to raise rice seedlings, so Zhongdiwang has compiled the four key points of rice seedling raising, listed in detail below for netizens' reference. Key point one, treatment of rice seeds: to improve the germination rate of rice, the seeds should be sun-dried before sowing, then treated with Baike (25% prochloraz)...
How can rice white-tip nematode disease be well controlled? Please provide an introduction to the methods.Rice white-tip nematode disease is also called white-tip disease and nematode heart-withering disease. It occurs in all major rice-growing regions across the country. It generally reduces yield by 10%-20%, and in severe cases by more than 30%. It mainly damages leaves and panicles. Rice white-tip nematode disease mainly occurs at the booting stage of rice; generally, light brown semi-transparent lesions appear at the tips of the flag leaf or the upper 2-3 leaves, which then gradually turn grayish-brown and become twisted white tips. Diseased panicles are shorter and smaller than healthy ones, with more blighted grains and lower 1000-grain weight.
Rice white-tip nematode disease can be controlled by referring to the following methods:
1. Strengthen plant quarantine: plant quarantine work should be strengthened, and it is strictly forbidden to introduce seeds from diseased areas.
2. Establish disease-free seed production fields: the irrigation and drainage system of the seed fields must be complete to prevent water carrying nematodes from flowing in. Before harvest, seed inspection should be carried out to ensure they are disease-free, then they should be harvested separately, threshed separately, and stored separately for use as seed.
4. At the seedling stage, use 2% Tianda abamectin + "Tianda 2116" Zhuangmiao Ling 600-fold solution, spray on the leaves, spraying 2 times consecutively, with an interval of 10-15 days between sprays.
