Occurrence and Control Methods of the Comstock Mealybug in Pear Orchards
(1) Occurrence patterns The Comstock mealybug belongs to the order Homoptera, family Pseudococcidae. Also known as the pear mealybug, plum mealybug, and mulberry mealybug. It generally produces three generations per year, overwintering as eggs and nymphs in hidden places such as cracks in the rough bark of tree trunks, bagged diseased and pest-infested fruits scattered in the orchard, weeds around the root zone, soil clods, and fallen leaves. Adults and nymphs suck the sap of tender buds, tender shoots, and fruits. Before bagging, it mainly damages tender buds and tender shoots, causing leaves to twist, swell, and shrivel, leading to branch dieback. After bagging, it burrows into the bags to damage the fruit, gathering in the calyx depression and stem depression, secreting white wax powder, contaminating the fruit, and sucking

Peach Tree Planting and Cultivation Methods and Key Technical Points
(1) Seedling raising and planting. For graft propagation, use wild peach rootstock; the seeds undergo stratification treatment and are broadcast sown in winter; bud grafting is done from June to August, or cleft grafting in early spring of the following year; the following winter the saplings can be lifted from the nursery. The planting spacing is 4 m x 5 m or 3 m x 4 m, with 500-840 trees planted per hectare. Planting can be done anytime from after leaf fall to before bud break. A peach orchard must not be continuously cropped, otherwise young trees will show noticeably weak growth, leaf chlorosis, new roots turning brown with many forks, and gumming on the branches and trunk. This continuous-cropping intolerance is more severe in sandy soil or soil with low fertility. The main cause is that the residual roots of the previous crop decompose in the soil

How to prevent and treat jujube witches' broom? Introduction to practical prevention and treatment methods
Jujube witches' broom is a devastating disease of jujube trees. After a jujube tree is infected, it shows the following abnormal phenomena: 1. Floral organs revert to ancestral form, the flower stalk lengthens to 3-6 times that of a normal flower, and the sepals, petals, stamens and pistils grow abnormally, becoming small pale green leaves. On diseased trees with stronger vigor, slender dwarf shoots may also sprout from the leaf axils of the small leaves, forming clusters of branches. 2. The main and secondary buds of developing branches and the fruiting mother branches sprout and grow multiple times a year, continuously producing small yellow-green branches and leaves, forming dense clusters of branches that do not easily fall off in winter. 3. On the trunk and branches of the whole tree, large numbers of latent buds that were originally dormant sprout massively

How to Treat Jujube Trees with Jujube Witches' Broom Disease? A Detailed Guide to Surgical Treatment Methods
1. Basis. The pathogen of jujube witches' broom disease is a mycoplasma-like organism, which mainly lives in the phloem of jujube trees and is conducted through the tree body via the sieve tube tissue. In winter, the mycoplasma-like organism moves from the aboveground parts to the roots to overwinter, and in the following spring flows back to the branches and trunk with the sap. On this basis, surgical treatment can effectively eliminate the mycoplasma-like organism. 2. Methods (1) Trunk ring sawing. Before leaf fall of the jujube tree and before sprouting the following year, starting from a point 40 cm above the ground on the trunk, use a saw to cut ring-shaped grooves in the trunk of the jujube tree. The requirement is to saw through the cortex, but not to damage the cambium. According to the severity of the disease,
