Description
Technical field
The invention belongs to crop disease prevention in agricultural production to cure the disease technical field, be specifically related to a kind of botanical sterilization preparation and the application in control rice blast thereof.
Background technology
Rice blast has another name called rice blast, and popular name is burnt pest, cracked a pest between the teeth, one of large important disease of paddy rice four.Rice blast has in rice district, various places of China and occurs in various degree, and since the nineties in 20th century, China's year occurring area is all more than 3,800,000 hectares, the general underproduction 10-20% of popular time, Severe Reduction can reach 40-50%, and even part field total crop failure, annual lost units reaches several hundred million kilograms.Rice blast is mainly caused harm blade, stem stalk, fringe portion, is divided into seedling pest, leaf pest, joint pest, panicle blast, grain pest according to period of causing harm, position difference.In rice seedling seedling stage and morbidity in tillering stage, blade can be made withered in a large number, time serious, full field is in burning shape, though some rice strain is not withered, but the young leaves extracted out not easily extends, and plant atrophy is not eared or extracted short and small fringe out, booting morbidity at heading stage can cause joint pest, panicle blast and grain pest seriously to occur, cause a large amount of dead ears or half dead ears, loss greatly.
Present agricultural production prevents and treats rice blast and mainly adopts chemical pesticide, as tricyclazole, Isoprothiolane, iprobenfos etc., wherein Isoprothiolane, iprobenfos etc. are because pesticide resistance and stopping using gradually the problem of environmental toxicity, and tricyclazole produces the upper medicament using more safer control rice blast, but mainly prevention effect, result for the treatment of is poor.The maximum of control rice blast biopesticide are kasugarnycin, to rice blast, there is good result for the treatment of, but have drug-fast report in different rice district, research finds to use kasugarnycin easily to make Pyricularia oryzae develop immunity to drugs continuously, and being therefore used alternatingly with different agents in the use procedure of field is reasonable solution.
Botanical pesticide refers to the agricultural chemicals utilizing plant resource explorations, have environmentally friendly, be easily absorbed by plants, crop production can be promoted or improve the advantages such as crop immunity.Along with country, the growing interest of society to food-safety problem, develop new and effective, environmentally friendly botanical pesticide, not only reduce the usage amount of chemical pesticide, improve agricultural product security quality, and be used alternatingly with other low toxicity highly effective pesticides, the drug-fast generation of crop germ can be delayed, extend the life cycle of product, reduce R&D costs, reduce the wasting of resources.
