Detailed Explanation of Key Technical Points for Controlling Two Diseases and Three Pests of Rice
The two diseases and three pests of rice refer to rice blast, sheath blight, rice stem borers, rice planthoppers, and the rice red-spotted black spittlebug. They cause great harm to rice and should be given attention for control. Rice blast: Long-term deep water irrigation or excessive drought, and one-sided application of nitrogen fertilizer lead to severe rice blast. There are three susceptible periods in the life of rice, namely the seedling stage, the peak tillering stage, and the heading and full heading stage. Neck blast has the greatest impact on rice yield and should be prevented early at the breaking stage and full heading stage. Rice blast is divided into: seedling blast, leaf blast, node blast, neck blast, and grain blast. Rice blast

Methods and Technical Key Points for Controlling the White-Backed Planthopper in Rice
Damage symptoms: Adults and nymphs gather in colonies at the base of rice plants and pierce and suck the sap, causing the leaf tips of rice leaves to lose green and turn yellow, and in severe cases the whole plant withers and dies. Damage during the heading stage can also cause difficulty in heading, blighted panicles, or browning of the panicles, along with many empty grains and other damage symptoms. Morphological characteristics: Adults have two forms, the long-winged type and the short-winged type. The long-winged adult is 4-5 mm long, grayish yellow, with a rather narrow vertex projecting in front of the compound eyes; the face has 3 raised longitudinal ridges, with the ridges light in color and the grooves dark, black and white sharply distinct; in the center of the scutellum on the thoracic dorsum grows a pentagonal white or bluish-white spot; in females the

What are the methods for controlling pests in off-season shiitake mushrooms?
Off-season cultivation of shiitake mushrooms refers to cultivation production in which shiitake mushrooms fruit from June to September. During this season, pests are rampant. If control measures are not adequate, yield and mushroom quality will be affected, so control should be strengthened. The main measures are: thoroughly clean up pest sources and thoroughly clean the toilets, chicken coops, and garbage piles around the mushroom shed. It is best if they can be relocated. If they cannot be relocated, regular pesticide spraying for pest control can be carried out. Particular attention should be paid to eggs in large manure piles. Among them, eggs of fungus gnats and manure flies can be killed through measures such as high-temperature fermentation and surface spraying. Shed
