Description
Technical field
The present invention relates to a kind of rice disease preventing agent of using, particularly prevent and treat medicine and the production method thereof of rice sheath blight disease.
Background technology
Banded sclerotial blight, is one of China paddy rice three large diseases, and all there is distribution in China Ge Dao district, but occurs generally with rice district on the south the Changjiang river, and early, middle and late rice all can occur.It is a kind of fungal disease being caused by Infection By Rhizoctonia Solani.Be that one of the most general Major Diseases occurs paddy rice, general early rice overweights late rice, often causes grain not full, and ghost rate increases, and serious caused plant lodging is withered.Be common in the gramineous plantses such as paddy rice, wheat, millet.Rice seedling to the fringe phase all can fall ill.Leaf sheath is caught an illness and at nearly water surface place, is produced dirty-green water soaking mode edge blurry stigma, the large ovalize of rear flaring or moire shape, and middle part is grayish green or taupe, and when humidity is low, middle part is yellowish or canescence, the middle part disorganization shape that is translucent, edge is dun.Several scabs of falling ill when serious merge and form large scab, are irregular moire spot, often cause yellow leaf withered, and stem stalk is injured symptom like blade, and the later stage is yellowish-brown, easy to break.
The germ of banded sclerotial blight mainly survives the winter in soil with sclerotium, also can on invalid body or on other hosts such as weeds in field, survive the winter with mycelium.During next spring spring irrigation, sclerotium flies at the water surface and other foreign material mix, and after rice transplanting, sclerotium adheres on the leaf sheath of the nearly water surface of rice strain, and condition is suitable to be born mycelia and invade leaf sheath tissue and cause harm, and aerial hyphae is infected again contiguous plant.The paddy rice shooting stage state of an illness starts to increase sharply, and disease is to horizontal, Longitudinal Extension, and the leaf sheath of take before heading is caused harm as main, heading backward inclined blade, the expansion of fringe neck.The sclerotium that falls into the water in early days also can cause rice strain and infect.Early rice sclerotium is the main source of infection of late rice banded sclerotial blight.It is popular that sclerotium chance suitable condition just can cause banded sclerotial blight, and hot and humid is another principal element of morbidity, and temperature 18-34 ℃ all can occur, the suitableeest with 22-28 ℃.Meet continuous rainfall, disease development rapidly.Temperature is down to below 20 ℃, and field relative moisture is less than 85%, falls ill slow or stops falling ill.
