What are the control methods for the wolfberry rust mite?
The wolfberry rust mite belongs to the family Eriophyidae. Swarms of mites densely cover the leaves and suck the sap, causing the leaves to turn rust-colored and drop early. Adult mites overwinter in bark crevices, bud axils and other places. The following year, after the wolfberry leaves unfurl in mid-April, they begin their damaging activity, and they begin laying eggs in late April. Late May to late June is the peak period of reproduction. After that, because the leaves turn rust-colored and the nutritional conditions deteriorate, the number of mites drops greatly. From late July to early August, new leaves emerge and a second reproduction peak appears. In mid-September reproduction slows, and after leaf fall in October the adult mites move to

Pruning Methods for Goji Trees in the Late Full-Bearing Stage
In the late full-bearing stage, the tree grows weakly, produces fewer shoots, and has short branches, with a marked decline in yield. At this time, the main task of pruning is to strengthen the tree's vigor. In addition to the general pruning carried out for trees in the full-bearing stage, the weakened scaffold branches or branch groups should also be renewed and rejuvenated. The specific method is to pinch off the growing tips of water sprouts in summer, and after side branches emerge, train them into new branch groups, while cutting back the scaffold branches above the water sprouts. If there are no water sprouts, cut back in spring pruning to the middle of 3-5 year old scaffold branches, or even a bit more severely, to stimulate the latent buds below the cut to sprout water sprouts,

Key Points and Operation Methods of Goji Berry Pruning Techniques Explained
I. Pruning during the young stage 1. Trunk-establishing pruning: Before the seedlings sprout, cut off the sprouts below 40 cm (branching zone) on the main trunk base stem, and cut the top at a plant height of 60 cm to 70 cm. 2. Summer pruning: From late April to late July, at intervals of 15 days, cut off the sprouting shoots within the branching zone of the main trunk, and cut back the lateral branches retained on the branching zone at 20 cm to 25 cm to promote the sprouting of secondary fruiting branches; among the vigorous branches growing upward from the lateral branches, select and retain 2 to 3 branches growing in different directions from the main branch, and cut them at 30 cm

Identification and Control Methods for Dactylium cobweb disease in lingzhi (Ganoderma)
DactyliumdendroidesFries belongs to the subdivision Deuteromycotina, class Hyphomycetes, order Moniliales, family Moniliaceae, genus Dactylium. 1. Morphological characteristics: The hyphae are pure white and cottony. The conidiophores are slender and sparse, with whorled branches arranged in a radiating pattern. The conidia are oblong, colorless, borne at the tips of sterigmata, solitary or in small clusters, mostly with 4 cells. 2. Disease development pattern (1) Transmission route: Dactylium lives in soil and is widely distributed in soils rich in organic matter.

Symptoms and Control Methods of Aspergillus Disease in Lingzhi (Ganoderma lucidum)
Aspergillus belongs to the Deuteromycotina, Hyphomycetes, Moniliales, Moniliaceae, genus Aspergillus. There are many species of Aspergillus, and the most widespread harmful ones are Aspergillus flavus (A. flavus Link) and Aspergillus niger (A. niger Van Tieghem). 1. Morphological characteristics: The hyphae are colorless, septate and branched, shorter and thicker than those of Mucor. The conidiophores arise from specialized thick-walled swollen foot cells of the hyphae, unbranched, with the apex swelling into a vesicle. The surface of the vesicle produces radial

Identification and Control Methods of Paecilomyces lucidus Disease
Paecilomyces belongs to the subphylum Deuteromycotina, class Hyphomycetes, order Hyphomycetales, family Hyphomycetaceae, genus Paecilomyces. The species commonly found in production is Paecilomyces variotii (p.varictBainier). 1. Morphological characteristics: The hyphae are white, transparent, and septate. The colony is earthy yellow and is often mistaken for Aspergillus flavus, commonly called yellow mold by mushroom growers. Conidiophores arise from aerial hyphae or cord-like hyphae; the phialides are slender and elongated, swollen at the base, tapering to a pointed tip, often curved, single to broom-like branched. Conidia are short cylindrical to long elliptical, smooth

How to Control Termites in Ganoderma lucidum Cultivation? Detailed Methods
Termites, also called white ants, belong to the order Isoptera, family Termitidae. Termites occur mainly in hilly and mountainous areas, and are less common in plain areas. Termites are a large family, most abundant in tropical and subtropical regions. In the cultivation of Ganoderma lucidum and other edible fungi, ants mainly bore into and feed on log segments. Damage characteristics: termites bore into and feed on log segments, causing the bark and wood of the log segments to separate, inhibiting the growth of Ganoderma lucidum mycelium and the formation of fruiting bodies. This in turn reduces Ganoderma lucidum yield. Morphological characteristics: winged adults are 27-29.5 mm long, with a wingspan of 45-50 mm, head

What are the control methods for goji root rot?
Goji root rot occurs commonly and causes serious damage; plants killed by the disease account for 3%-5% each year, causing great losses to goji production. According to research by Lu Zhankui and others at the Ningxia Academy of Agriculture and Forestry Sciences, root rot symptoms fall into the following two types: (1) Root decay type. Roots or the root crown show varying degrees of decay and peeling, the stem vascular bundles turn brown, and in damp conditions a white or pink mold layer grows on the diseased area. It can further be divided into two types: small-leaf type and yellowing type. ① Small-leaf type: leaf emergence in spring is delayed, leaves are small, branches are stunted, flower buds and

Detailed Guide to Dried Goji Berry Production: Processing Methods from Fresh Fruit to Dried Fruit
I. Sun-Drying Method 1. Mix freshly picked goji berries evenly with alkaline water, then spread them evenly in goji trays ("goji tray": a specialized tool for sun-drying or oven-drying goji berries. Generally, it is a wooden frame nailed together from wooden strips, 90 cm long and 60 cm wide, with window screen nailed to the bottom of the wooden frame, and a crossbar nailed below the window screen. The goji berries are spread on top of the window screen. Note: some use cardboard or bamboo mats, but none have better breathability and ventilation than window screen). Dry in a shaded, well-ventilated place (one day is preferable). Wait
