Key Technical Points for Integrated Control of Rice Diseases, Insect Pests, Weeds and Rodents
1. Suitable areas: all rice-growing areas in Guangdong Province. The rodent control technology is suitable for controlling house mice in agriculture, forestry, livestock and poultry farming, and urban areas of Guangdong Province. 2. Key technical points for rice disease and insect pest control: (1) Agricultural control: A. Select disease- and insect-resistant, high-yielding, high-quality varieties. B. Sow and transplant at the appropriate time. C. Rational close planting and fertilization. For seedling throwing, 40 trays per mu (560 holes) is appropriate; for transplanted fields, about 20,000 hills per mu (6X5 cun), that is, about 80,000-100,000 seedlings, is appropriate. For basal fertilizer, it is recommended to apply more organic fertilizer; according to soil fertility and yield, apply an appropriate amount of nitrogen fertilizer in the early and middle stages (about 10 kg of pure nitrogen per mu), and increase the application of phosphorus and potassium fertilizers.

Occurrence of Tulip Diseases and Integrated Control Methods
Tulip is a perennial bulbous herbaceous plant of the genus Tulipa in the family Liliaceae, also known as foreign lotus, grass musk, peony lily, etc., and is one of the most popular cut flowers in the world. With the adjustment of industrial structure, many places in Jiangsu Province have formed tulip fresh cut flower bases. However, in the production process, we found that every stage may be harmed by fungal, bacterial and viral diseases, thereby affecting the normal growth of plants, reducing the quality and ornamental value of cut flowers, and in severe cases causing devastating damage. Therefore, preventing the occurrence and development of tulip diseases is the

The "Huishan disinfection" method in integrated silkworm disease control
Disinfection is carried out after the silkworm rearing is finished. Because after the silkworms mount the cocooning frames and spin cocoons, and after the cocoons are harvested, there are often many rotten cocoons, dead diseased silkworm bodies and silkworm droppings left behind, especially during the summer and autumn rearing seasons, this is the time when pathogens are most concentrated. If disinfection is not carried out in time, it poses a great threat to the safety of rearing the next batch of silkworms, so a thorough disinfection must be carried out promptly, which is generally called "Huishan disinfection" in production. The method is mainly to gather together the various silkworm rearing tools used for rearing and mounting on the cocooning frames, first spray and disinfect them once with 1%-2% lime slurry or bleaching powder solution with 1% available chlorine, and then

Occurrence and Integrated Control Methods of Sheep Nasal Bot Fly
Cause: Sheep nasal bot fly is a disease caused by the larvae of the sheep nasal bot fly parasitizing the nasal cavity of sheep, mainly affecting sheep (Ovis aries). The adult sheep nasal bot fly directly deposits larvae, and the larvae become adults after passing through the pupal stage. Adult sheep nasal bot flies appear from May to September each year. After mating, the male fly dies, and the female fly rests until the larvae inside her body develop before flying and becoming active, depositing maggots in the nostrils of sheep to breed larvae. The first-stage larvae attach to the nasal mucosa of sheep and gradually migrate inward, molting into second-stage larvae in the nasal cavity and frontal sinuses, and by the spring of the following year, they develop into mature third-stage larvae.

Key Points for Integrated Control of Powdery Mildew on Schisandra chinensis
1. Field symptoms Powdery mildew mainly damages the leaves of Schisandra chinensis, and in severe cases the fruit, petioles and stems are also affected. In the early stage of leaf infection, small white powdery mildew spots appear, gradually expanding and merging into patches, and the mildew layer thickens, like a layer of flour scattered on the leaf surface. On the underside of the mildew spots, small chlorotic spots initially form, expanding into irregular patches as the disease develops. In the late stage of the disease, black particles are produced in the mildew layer, causing moldy staining and fruit drop, reducing yield while also lowering quality. 2. Disease occurrence The powdery mildew pathogen of Schisandra chinensis belongs to the genus Erysiphe in the Ascomycota, and the conidia are mostly cylindrical, with a few being cylindrical-columnar, elliptical or long-oval. In the Fengcheng area, the pathogen overwinters as cleistothecia on diseased plant residues, and in May to June of the second year produces ascospores and conidia for infection, with July to August being the peak period of disease occurrence. The disease can occur at temperatures of 20-28°C, with 25-26°C being the most suitable. The disease is severe in mountainous areas above 1000 m in altitude; it is severe where management is poor, nitrogen fertilizer is applied excessively, and planting is too dense; 1-2 year old Schisandra chinensis plants are lightly affected, while those over 3 years old are severely affected.

What are the integrated pest and disease control measures for mushrooms?
Mushrooms are the main cultivated edible fungus variety in Zhangpu County, Zhangzhou City, Fujian Province. However, pests and diseases have long plagued the vast number of mushroom growers. The integrated control measures are described below: (1) Strengthen cultivation management. 1. Disinfection of the cultivation house. For disinfection of the cultivation house, a mixed solution of formalin and dichlorvos can be used for fumigation. Before fumigation, first moisten the floor, walls, bed frames and daily tools by spraying, and seal up cracks. For every 100 sq m, use 1 jin of formalin and 150-200 g of dichlorvos in a pot, add 5 times the amount of water, then place it on a stove and heat. After lighting the fire

How to prevent and control pests and diseases of edible fungi? A detailed explanation of integrated control techniques
Edible fungi belong to the macrofungi, and the environmental conditions required for their growth and development are also suitable for the occurrence, growth and reproduction of many pests and diseases. If the control of the ecological environment is not taken seriously, and necessary preventive measures are not taken in the early stage, contaminant microorganisms and various insect pests will occur in large numbers. In cultivation, following the integrated control policy of giving priority to agricultural control, reasonably combining biological and physical methods, and using chemical control as a remedial measure, and giving full play to the complementary advantages of various control methods, will be of very great significance for achieving high quality and high yield of various edible fungi. 1 Edible

Integrated Control Methods for Soybean "Fire Dragon Seedling"
In Wudalianchi City, Heilongjiang Province, the soybean area is 950,000 mu, with a continuous cropping area of 930,000 mu, accounting for 97.8% of the soybean sown area. Through investigation, the area affected by soybean "Fire Dragon Seedling" is around 96.5%, with most yield reductions between 20 and 50%, and some plots reaching total crop failure. It can be said that due to the influence of the market economy, the continuous cropping area of soybean cannot be controlled, but through integrated control, the occurrence of soybean "Fire Dragon Seedling" can be reduced, enabling soybean to achieve high and stable yields. The integrated control techniques for soybean "Fire Dragon Seedling" are as follows:
