The hopper is also known as the ash worm and the tail worm. The main pests of the medicinal and medicinal fungi are the mushroom mites and black horned worms. The main pests that harm the fruiting bodies of edible and medicinal fungi are spring worms, nematodes, and mushroom mites. The worms and nematodes are mainly harmful to the young mushroom buds, and the mushroom mites mainly endanger the mature mushroom body. These pests are extremely harmful to the production of edible and medicinal fungi and must be carefully prevented.
Pinacol is a white solid organic compound. It is a diol that has hydroxyl groups (-OH) on vicinal carbon atoms.
Pinacol can be used with borane and boron trichloride to produce useful synthetic intermediates such as pinacolborane, bis(pinacolato)diboron,[3] and pinacolchloroborane.
It may be produced by the pinacol coupling reaction from acetone
As a vicinal-diol, it can rearrange to pinacolone by the pinacol rearrangement, e.g. by heating with sulfuric acid

Mushroom mites, nearly white spherical, translucent, larva white, body shape similar to adult worms, suede after dormancy, color gradually darkening, silver-gray, grayish black when clustering, like soot, adult shape like flea, body length 1.2-1.5 Millimeter, short tentacles, wingless, 8 pairs of feet, often crawling rapidly on the surface of culture material and fruit body, with bouncer at the end, usually in the form of bounce, jumping height up to several 10 cm high, body surface with grease, Not afraid of water, when floating in the water, it can float a layer of water, like bran, flowing with water, in a suitable environment, the reproduction speed is fast, 6-7 generations can occur every year, and a large number occurs at 20-28 °C. Often clustered in the roots of the back of the fruiting body and in the pores of the leaves. Especially in the young mushroom stage, the original base will be covered by the worm body, so that the mushroom body is sallow, and the infected bacteria rot and stop growing. The hopper is an indicator pest that is too humid and has poor hygienic conditions.
The prevention methods are as follows:
1. The planting site must choose a better place to avoid low-lying squat toilets and garbage dumps to reduce pollution opportunities. Sanitary, ventilated, water source strips 2. Before the growth of fruiting bodies, 0.1% of low-toxic phoxim can be sprayed in the surrounding environment for 1-2 times for prevention. If the worm is found, the same method can be used for prevention and treatment. (1) There are many types of nematodes, such as blood nematodes, mushroom mites, and knot worms. The blood worm, the worm body is 3-4 cm long, very slender, like a bloodline head, clustered in the soil layer 1-2 cm deep around the mushroom bud, which harms the young mushroom buds, so that the growth of the mushroom body stops sallow or rot. (2) Mushroom mites are the main pests that endanger mature mushrooms. The length of the body is so large that it penetrates into the inside of the mushroom body, causing the quality of the mushroom body to drop seriously and losing the value of the commodity. When a mushroom sputum occurs, a spider web or a wormhole can be found between the roots of the mushroom body and between the leaves. Control measures: 1. Partial spraying of pesticides 0.3-0.5% trichlorfon water, sprayed around the killing and killing.
3. Comprehensive prevention and control, clean the surrounding environment. Keep clean water. Found that pests and diseases are treated in time to prevent transmission
