First, rice blast disease: There are mainly leafhoppers and panicles. Rice leaf plague mainly damages the leaves and forms fusiform lesions on the leaves. The center is greyish-white with reddish-brown edges. There are yellow halos around the lesions. On the back of the lesions, there is a layer of gray mold on the back of the lesions; panicle blasts are a serious hazard and occur in rice ears. In the neck, brown dots were formed in the early stage, and the ear and neck became brownish after expansion, resulting in withered white spikes. Late lesions caused by rickets, branches, or rachis caused false spikelets. According to county plant protection station July 25-29 in Xiaban City Xinjiazhuang, warehouse, three, Deng Shang and other places of investigation, rice leaf temperature disease occurs lightly, the field rate of 10-15%, disease plant rate of 0.5-2% Sporadic occurrence of spikes and neck ridges occurred in August and the county’s microclimate in the field facilitated the occurrence of panicle rot. Control methods: At the beginning of the disease, spray with 25% allicin powder 800 times, or spray with 20% tricyclazole WP 1000 times, or 25% with 25% Ami-Site suspension, watering 40-60 Kilograms of evenly sprayed leaves are sprayed once every 7-10 days and sprayed 2-3 times. Second, the rice sheath blight: moderate occurrence, partial occurrence of heavy emphasis, the future will be aggravated. In the recent survey, the diseased field rate was 25-30%, the disease-clustering rate was 5-15%, and the diseased plant rate was 3-10%. When the disease-contamination rate reached 10%, medication was used for prevention and treatment. Control methods: 50,000 mugangmycin soluble powder 100-150 grams, watered 75-100 kg, or 20% dried water soluble powder 600 times, or 70% thiophanate-methyl wettable powder 700 times Liquid, aimed at the lower part of the rice plant spray, spray once every 7-10 days, and even spray 2-3 times. Third, rice smut disease: Occurs in the panicle, damage part of the grain, in the rice break, ear, flowering period of rain and sunshine, recent rainfall, field humidity is too high, is conducive to the incidence of rice smut disease. Control methods: 100-150 ml of 5% Jinggangmycin water for rice during the flowering stage, 50-75 kg of water for spraying the upper part of the leaf, or 20% of Qufengxingxing wettable powder 100-150 g per mu; or Mu with 30% love seedlings (difenoconazole) EC 15-20 ml watered 40 kg, stir the foliar spray. Fourth, rice pests: mainly rice borer borer, rice borer, rice water weevil, rice borer, three generations of armyworm and so on. Control methods: 1, acres with 1% celangulin EC 10 ml, watering 50-70 kg evenly spray. 2, 4.5% beta cypermethrin EC 1500 times spray. 3,5% pyrethrin EC 1000-1500 times spray. 4, with 0.3% matrine aqueous solution in the armyworm 2, 3 instar larval stage application, 500-830 ml per acre medication, add water 50 kg, for routine spray Diagnostic Equipment,Hpv Dna Sequencing,Clinical Dna Gene Sequencer,Pcr Molecular Test Nanjing Superyears Gene Technology Co., Ltd. , https://www.superyearsglobal.com
