Disease conditions of the chicken-claw fungus in pollution-free cultivation
The shaggy ink cap mushroom (Coprinus comatus) is deeply favored by mushroom growers for its rich nutrition, delicious taste, tender and smooth flesh, and strong market demand. It has been widely cultivated across the country with very broad development prospects. However, in actual cultivation, mushroom growers are often troubled by a kind of Xylaria (commonly known as chicken-claw fungus). Due to neglected prevention and control, by the time large-scale infection appears, they randomly use some high-residue pesticides for treatment, which not only has no effect but also often causes the pesticide residues in the finished mushrooms to exceed the standard and affects product sales. For example, in mid-October 2006, Hubei Province

Causes of Tea Geometrid Outbreaks and Pollution-Free Control Methods
Tea geometrid, also known as the arching worm, measuring worm, and hanging-silk worm, belongs to the order Lepidoptera, family Geometridae. In Liandu District, this pest is mainly distributed in tea areas such as Bihu and Lixin, and is a voracious pest. If control is not timely, it often causes severe reductions in summer and autumn tea yields, and leads to decline in tree vigor, seriously affecting tea production. In previous years it occurred every year, but the damage was not great. In August 2007, this pest broke out over a large area in the Huanglingshang tea garden of Lixin Township, not only severely affecting the tea yield of that season, but also causing decline in tree vigor and poor cold resistance

Detailed Explanation of Key Points of Pollution-Free Pear Bagging Technology
① Bag selection: The selection of paper bags for pear bagging should be reasonably made according to the tree growth conditions in the orchard, production goals, and economic capacity. Since the main purpose of bagging pears is to improve the smoothness and finish of the fruit surface, lower-cost single-layer bags can be chosen, such as Kaixiang bags, Tianjin bags, etc.; for those aiming to improve quality, double-layer bags with a black inner bag can be chosen. ② Bagging period: Pears should be bagged after fruit thinning is completed in early to mid-May; the best bagging time is on sunny days from 9:00 to 11:00 in the morning and from 2:00 to 6:00 in the afternoon. ③ Bagging
