The outbreaks of rice pests and diseases in China are frequent, the damage is serious, and the pressure of prevention and control is large. It is of great significance to ensure the safety of rice production and food production. According to the expert consultation of experts from the National Agricultural Technology Center, rice pests and diseases in 2011 continue to show a serious ecological situation, which is more important than in 2010. It is estimated that an area of ​​1.39 billion mu will occur. In order to do a good job in the prevention and control of major rice pests and diseases in 2011 and minimize pest damage losses, this plan is formulated. First, prevention and control targets The pest prevention and treatment rate reached over 90%, the green prevention and control technology application area reached over 30%, the specialized prevention and control area reached over 15%, the overall control effect reached over 85%, and the pest and disease damage loss rate was controlled. Within 5%, the use of pesticides in paddy fields was reduced by more than 10%, and the use of highly toxic pesticides and pesticides containing pyrethroids was eliminated. Second, the prevention and control strategy is centered on the rice-field ecosystem, with major pests and pests as the main target, seizing key areas and key periods, and preventing and controlling key pest eradication and critical disease epidemics, and mainly promoting green prevention and control technologies. Rationally use drugs, advance specialization prevention and control, control losses of diseases and insect pests below the economically permissible level, reduce the use of chemical pesticides, protect the ecological environment of rice fields, and strive to achieve sustainable treatment of rice diseases and insect pests. III. Prevention and Control Technology Measures (I) Prevention and Control of Key Areas and Targets South China Rice Region: Including Guangdong, Fujian, Guangxi, and Hainan Double Cropping Rice Planting Areas, with rice planthoppers, rice leaf roller, Sanhua rice dumplings, southern rice black Dwarfism, rice blast, sheath blight, and rice smut are the main targets. The middle and lower reaches of the Yangtze River and the Changjiang-Huaihe Region include Jiangxi, Hunan, Hubei, Anhui, Jiangsu, Zhejiang, Shanghai, Henan, central and southern single- and double-season mixed rice areas and single-crop rice cultivation areas, with rice planthoppers, rice leaffolders, and two Huayu, southern rice black-streaked dwarf disease (mainly attacking stripe leaf blight and black-streaked dwarf disease in Jianghuai and Huanghuai rice region), rice blast, sheath blight, and rice smut were the main targets. Southwest rice area: including single-crop rice planting areas in Yunnan, Guizhou, Sichuan, Chongqing, and northern Guangxi. It focuses on rice planthopper, rice leaf roller, leaf borer, rice blast, rice smut, southern rice black-streaked dwarf disease. Object. The northern rice area includes the single-season rice planting areas in Heilongjiang, Jilin, Liaoning, and northern Hebei. Rice blast, rice stem borer, and stripe blight are the main targets. (II) Main technical measures Rice planthoppers: The prevention and control of whitebacked planthoppers and brown planthoppers in the middle and late stages of rice growth are important. The southwestern rice area should pay attention to the prevention and control of rice migration in the early stage. Before the booting of rice, natural enemies should be controlled to play a role in harm control and plant compensation to reduce medication. More than 1,000 nest insects at the heading stage of the booting stage, and the control index at the ear stage of hybrid rice can be relaxed to more than 1500 insecticidal levels. It is preferred to control insecticides at the younger stage of nymphs, and to preferentially select insecticides such as insect growth regulators to be relatively safe to natural enemies. Variety, promote the use of high-content single agent, avoid the use of low-level compounding agents. Jiangnan, Jianghuai, and Huaihai Bay area should ensure the control of Laodelphax striatellus during transplanting and transplanting, and control the spread of leaf blight and black-streaked dwarf disease in Laodelphax striatellus. Southern rice black-streaked dwarf disease area, do a good job of impregnating or seed dressing of mid-to-late-season rice seedlings and seedling stage rice planthopper prevention and control, make good Putian send martial medicine, early stage of tillering prevention and control, prevent white-flying planthoppers, spread southern rice, black stripe dwarf Diminished disease. The rice leaffolder (Cnaphalocrocis medinalis): It focuses on the prevention and control of the rice leaf roller in the middle and later stages of rice leaf crucian carp. Artificial release of the rice leafhopper Trichogramma edulis in the egg stage will reduce the population size, and Bt will be preferred during the peak period of egg hatching to young instar larvae. Bio-pesticides control, prevention and control indicators 100 bundles of 50 tips. Locust: rice anti-drying at delivery, anti-white spike at heading. Spring overwintering larvae and ploughing tillage stage will reduce the source number of insects. At the beginning of each generation, insect pheromones were used to trap and kill adults, egg stages released Trichogramma, and larval stages were treated with Bt. Persisting in chemical prevention and control according to prevention and control indicators, the rate of dry-stem strains reached 3% during the tillering period of the clams, and the number of eggs per mu in the booting stage to the heading stage reached 50, which was controlled at the peak of egg hatching period. The rice field with 40 eggs/mu per mu was used to control the application of rice at the beginning of rice breakage and heading. Rice blast: Focus on the prevention of leafhoppers and panicle blasts from the tillering stage to the heading stage. Plant disease-resistant varieties and implement diversified planting to avoid excessive and late application of nitrogen fertilizer. Early rice and single-season paddy fields are used to make martial medicines, and when the acute lesions or the onset centers appear in the field during the tillering period, chemical control is performed, and the panicle blasting stage is applied to prevent ear blasts. Promote the use of high-level single-dose pesticides and avoid the use of low-level compounding agents. Sheath blight: focus on the prevention and treatment of late rice tiller to booting heading. Strengthen fertilizer and water management, do a good job of fitness cultivation, and field drying at the end of the crop is good, and when the field disease cluster rate reaches 20%, chemical control is performed. Southern rice black streaked dwarf disease: Adopting the strategy of “practicing pests and disease prevention†by “grasping fields and protecting fields and grasping the late stage of conservationâ€, prevention and control of rice planthoppers in Putian and Honda early stages of single- and double-season late rice varieties were performed. Focus on pesticide seed dressing or soaking and transplanting with drugs, Putian and Honda early poisonous whitebacked planthoppers move in, use quick-acting and persistent drugs and anti-virus agent control. In the single-cropping areas of South China and the middle reaches of the Yangtze River, the planting period can be appropriately adjusted to avoid the migration period of whitebacked planthoppers in sensitive period of rice. Putian should be far away from susceptible rice fields and corn fields, use insect nets or non-woven cover to protect or focus on conservation, and use sterile seedlings. Frequently growing areas increase the transplant density and reserve spare seedlings. In the field, it was found that the susceptible plants were removed or stepped into the mud in a timely manner to reduce the local source of poison, and to make up the seedlings from the upper layer of the Jian Cong (strain), and the severe disease field should be ploughed and replanted in time. Rice smut disease: use resistant varieties to avoid overdose and late application of nitrogen fertilizer and improve rice disease resistance. Focus on the prevention of rice at the end of booting, that is, 7-10 days before the rice headings, in case of appropriate weather, 7 days after the second application of pesticides. Fourth, specializing in prevention and control of the main push technology (a) deep plowing irrigation water control plutonium control plutonium use of weak resistance characteristics of pupation in the pupal stage, in the spring overwintering locusts pupate stage uniform plowing winter fields, green fertilization fields, irrigation deepwater dipping Immersion of rice piles for 7-10 days can kill 70%-80% of earthworms and effectively reduce the number of insects. Farming in the winter after the harvest, but also have a certain effect. Double-season rice continuous cropping, early rice harvest, prompt plowing, flooding and inundation of rice piles can kill more than 90% of the locusts. (ii) Selection of Disease Resistance Techniques for Resistant Varieties Selection of Rice Varieties Resistant to Rice Blast, Rice Quercus, and Stripe Blight, Eliminating Poorly Resistant, Susceptible Disease Varieties, and Rotating Plants of Long-term Crops in Time to Prevent Diseases The fundamental measure. (III) Insect sex pheromone pheromones II larvae technology is started in the winter worming stage of the winter plague and the main moth dying moth period. The field pheromone sex pheromone is set in the field, one trap is placed per acre, and one trapping core is built. Replace the lures on behalf of one generation and the trap is 30 cm above the top of the rice plant. Concentrated use, you can seduce adult insects and reduce the amount of eggs and population in the field. (IV) Seed Disinfection and Transplantation with Drugs to Prevent Pests and Diseases Early Rice Soaking with Miramide to Prevent Bakanae and Rice Blast. Single-season rice and double-season rice were dressed or impregnated with imidacloprid to prevent the emergence of rice planthoppers in seedling stage, black-streaked dwarf disease, southern rice stripe virus disease, and rice thrips. The seedlings shall be sprayed and sent for 3-5 days prior to transplanting, so as to prevent or reduce the occurrence of field diseases and insect pests. Double-season rice was used to send the herbs to prevent aphids and rice blast. Single-season rice and double-season late rice were used for the delivery of antibiotics for the prevention of rice thrips, aphids, rice planthoppers and spread of viral diseases. (v) Bio-pesticides for controlling pests and diseases 1. Bacillus thuringiensis (Bt) technology for the control of rice stem borers and rice leaf roller. The control of Bt in the hatching period of S. japonicum and C. medinalis in the hatching period of eggs has good control effect. Especially in the early stage of rice growth, the use of Bt can effectively protect natural enemies in paddy fields and maintain the ecological balance of paddy fields. Note that Bt is highly toxic to silkworms and is used with caution in rice fields near mulberry fields. 2. Bacillus wax Bacillus, Bacillus subtilis control rice blast disease technology. In the case of acute lesions or episodes of leaf (seedlings) emergence and rainy weather at the heading stage of breakage, uniform sprays of Bacillus cereus or Bacillus subtilis are used. Once the shoots are sprayed again, they are sprayed one time, which is good for rice blast. Prevention and control effects, do not pollute the environment, and are safe for rice. 3. Well waxy Bacillus control rice smut disease technology. In the 7-10 days before the heading and heading of rice at the booting stage, application of the well Bacillus cereus can effectively prevent rice smut, and it can also treat sheath blight. (6) Common measures for the protection and utilization of natural enemy pest management techniques include: planting wild plants such as sesame seeds and soybeans, protecting and utilizing natural enemies such as spiders, parasitic bees, ladybugs, grasshoppers, and frogs; releasing Trichogramma to prevent stem borer and rice Leafhopper. (7) Light trapping and pest control technology A frequency-vibration type insecticidal lamp is installed every 30-50 acres of rice fields. The bottom of the insecticidal lamp is 1.5 meters away from the ground. The lamp is turned on after the occurrence of adult pests, and the lamp is turned off after dawn. A variety of pests, such as Siniperca chuatsi, S. indica, S. involucrata, rice planthopper, rice planthopper, etc. (8) Rice-duck co-education and pest control grass-grass technology After transplanting rice 7 days to 10 days after transplanting, the ducklings will be put into the paddy field for 15 days or so, and 10-20 ducks will be released per acre of rice field. Ducks before heading. Through the feeding activities of ducks, we can reduce the occurrence of diseases and weeds such as sheath blight, rice planthoppers and weeds. (9) Efficient and low-toxic chemical pesticides for controlling pests and diseases Pyripidone, buprofezin, isoprocarb, and fenthrin prevent and control brown planthopper, thiamethoxam, and nitenpyram in the control of whitebacked planthoppers and planthoppers, propibromide Phosphorus, Chlorantraniliprole, Emamectin Control Cnaphalocrocis medinalis, Tricyclazole, Prochloraz, Indazole, etc. Control of Rice Blast, Cooperative Use of Antiviral Agents and Insecticides such as Ningnanmycin Prevent virus disease such as stripe blight, southern rice black streak dwarf disease, difenoconazole, tebuconazole to prevent rice smut disease.
