What are the methods for controlling pests and diseases of jasmine?
1. Diseases ① Brown spot: promptly prune away diseased leaves and diseased branches, and spray the foliage with 80% zineb wettable powder at 500-700 times dilution, or 80% mancozeb wettable powder at 400-600 times dilution, spraying once every 10-15 days, for 3-5 consecutive sprays. When spraying, the front and back of the leaves should be evenly covered. ② Southern blight: in the early stage of the disease, spray the base of the plant and the surrounding soil with 50% amobam aqueous solution at 1000 times dilution, and after 7-10 days, spray once more. After that, use 70% thiophanate

Detailed Explanation of Methods for Preventing and Controlling Edible Mushroom Diseases and Pests
Bacterial Rust Spot Disease I. Harmful Symptoms This disease often occurs on mushroom bags or mushroom beds, with mucus on the surface and yellowing mycelium; the pathogen can produce toxins, causing spots to appear on the caps. The spots are brown, round or oval, with a dark outer edge and irregular shape; when humid, the center of the cap is grayish-white with milky-white mucus; when the air is dry, the central part is slightly sunken. Spots on the stipe are diamond-shaped or oval. II. Conditions for Onset Unsuitable climate, encountering high temperature and high humidity, with relative air humidity above 95%; poor

Detailed Guide to Identifying and Controlling the Main Diseases and Pests of Oyster Mushrooms
The most serious damage is contamination by foreign molds. Common contaminating molds include Trichoderma, green mold, yellow mold, Rhizopus, and others. The main control methods are: choose materials free of mold, compost and ferment the substrate and sterilize it, strictly disinfect the cultivation site, and promptly remove any contaminated material. Provide proper ventilation to prevent excessively high temperatures and humidity. Oyster mushroom cultivation also frequently shows physiological disorders: ① Partial death of small mushrooms: when there are too many small mushrooms, some will die, mainly from "starvation" due to insufficient nutrients; spraying water too early or excessively high humidity can also cause small mushrooms to die.

What are the methods for controlling pests and diseases of jasmine?
Diseases of jasmine during its growth period include: jasmine stem rot and southern blight; pests include: jasmine leaf borer, scale insects, and carmine spider mite. (1) Jasmine stem rot. This disease occurs at the base of the stem. In the early stage, the lesions are brown spots with a water-soaked appearance. The lesions extend longitudinally into streaks. The edges are dark brown, the interior grayish-brown; in the later stage, the lesion tissue rots and splits longitudinally, and black granular bodies appear. This disease occurs year-round during greenhouse maintenance, and is especially severe in early spring. It also occurs in August-September when plants are maintained outdoors. High temperature and humid conditions

Detailed Guide to Identifying and Controlling the Green Peach Aphid
The green peach aphid (Myzus persicae) causes extremely widespread damage. Adults and nymphs gather in groups on the undersides of leaves and on tender shoots to suck sap. Infested leaves curl irregularly toward the underside, which affects the growth of new shoots on peach trees and spreads viruses. The green peach aphid can damage more than 300 species of plants, making it one of the most difficult pests to control. Winged viviparous females are green or yellow-green; brown and reddish-brown forms also occur, with colors varying according to the host; wingless viviparous females are green, yellow-green, apricot-yellow, and reddish-brown; nymphs are small and pale red; eggs are mostly laid on the host's shoot tips, bud axils, and small branch forks

Degradable-film controlled-release fertilizer for rice successfully developed in Hunan Province
The Soil and Fertilizer Institute of Hunan Province has developed a degradable-film controlled-release fertilizer for rice that can be widely applied in rice-growing regions of China with no side effects. Using natural and semi-natural polymer materials as the main coating components and adopting a self-developed new fluidized dual-spray-bed coating process, the Soil and Fertilizer Institute of Hunan Province developed a degradable-film controlled-release fertilizer whose nutrient release can be artificially controlled within 30 to 330 days. This controlled-release fertilizer is non-toxic, completely degrades within 2 years after being applied to the soil with no residue, and can reduce fertilizer pollution of the atmosphere, soil, water bodies and other environments.

Which varieties can be used for controlling the rice stem borer (Chilo suppressalis)?
(1) Fipronil. The recommended dose is 1.5-2.5 g active ingredient per mu. The key application points are: spray at the peak hatching stage of the rice stem borer eggs; the field may be kept with or without a water layer. Because fipronil is highly toxic to bees and aquatic organisms, and especially highly toxic to shrimp and crabs, do not use it in bee-keeping areas or shrimp and crab farming areas. If it must be used, it is recommended to drain the field water before application. After a rice field has been treated with fipronil, do not discharge the field water into fish ponds or rivers and ditches. (2) Fipronil + trichlorfon

Detailed Methods and Techniques for Preventing and Controlling Pests and Diseases of Mountain Lilies
Lily gray mold, anthracnose, and late blight are common diseases of plants in the Liliaceae family. If not controlled in time, they will cause reduced yields. (1) Lily gray mold, also known as leaf blight, belongs to the Deuteromycetes. It mainly occurs on stems, leaves, and flowers, and mostly damages the tips of young leaves, causing the stem growing points to soften and rot. When it occurs on leaves, it forms yellow or reddish-brown spots with water-soaked margins. In humid weather, gray mold-like substances are produced on the diseased parts. Control: In the early stage of disease, spray 1:1:150 Bordeaux mixture or mancozeb 600-800 times dilution, spraying 2-

Citrus pests can be controlled with Pinellia ternata juice.
Take 1 kg of freshly dug Pinellia ternata (crow-dipper) tubers, chop them, add 3 kg of water and grind into a slurry; for every 1 kg of slurry, add 30-40 kg of water and spray it on citrus trees; or chop 1 kg of Pinellia ternata, add 5 kg of water and boil for 2 hours, then after filtering dilute the stock solution 20-30 times and spray. The control effect against citrus scale insects, red spider mites and aphids reaches over 98%.
