What are apricot diseases and insect pests?

What are apricot diseases and insect pests? What are the hazards? Is there any way to prevent it? We also ask experienced netizens to help introduce apricot diseases and insect pests, such as apricot tumor disease, almond wasp, apricot fruit weevil, mulberry shell insect, apricot nut shell insect, and so on. The farming network has sorted out the harm and control methods of various diseases and insect pests, which are listed below for netizens' reference. First, the harm of apricot tumor disease: apricot tumor disease generally occurs on new shoots, leaves, flowers and fruits of apricot trees. Generally speaking, the disease begins to appear when the new shoot is more than 15 cm long after falling flowers. The injured shoot elongated slowly, showing dark red at first, then turned yellowish green, the upper yellowish brown raised slightly, the diseased shoot was easy to dry up, and the result was retarded and dried, shedded or suspended on the branch. The prevention and treatment method of apricot tumour disease: when the shoot and leaf show the disease, cut off in time, and burn it centrally, so that it can be controlled basically for 2-3 years. Second, the harm of almond wasps: before fruit ripening, the larvae damage apricot fruit and cause early fall. The control methods of almond bees are as follows: 1. Pick up the fruit in time and bury it deeply; 2. When the apricot fruit is as big as beans (May), when the larvae lay eggs, spray 2500 times deltamethrin or kill permethrin, and the effect is good. Third, the harm of apricot fruit weevil: from April to June, adults eat young buds and flower buds, lay eggs after falling flowers, and harm fruit. The control methods of apricot weevil are as follows: 1, artificially capture adults during flowering; 2, pick up fruit and destroy it in time; 3, spray 200 times 50% wettable DDT to kill adults. Fourth, the harm of mulberry shell insects: from late March to late October every year, the growth of the injured branches is weak, and even withered. The control methods of mulberry shell insects are as follows: (1) spraying 5-degree stone-sulfur mixture or using 3-fold solution of monocrotophos to dry the branches before germination; (2) brushing off the overwintering female adults on the branches in winter or early spring; and (3) spraying 0.3-0.4 degrees stone-sulfur mixture during the larval incubation period (June). Fifth, the harm of apricot beetle insects: one generation a year, the nymph overwintered in the rough skin of the branch, began to suck the shoot juice in April, and the whole branch died when it was serious. The control methods of apricot hard shell insects are as follows: 1. In the first ten days of May, when the worm is still soft, brush it off with a hard brush; 2. Spray 5-degree stone-sulfur mixture or diesel oil emulsion with 5% oil content before germination in early spring; 3. Spray 0.3-0.5 degree stone-sulfur mixture during larval incubation.
