Momo Mosquito
Peach aphids damage the tops, leaves and young fruits of peach trees. Adults and larvae cluster on the back of the leaf, and the damaged leaves roll longitudinally from the leaf margin to the back of the leaf, the tissue becomes hypertrophied, fades green, and excretes mucus to pollute the branches and leaves, inhibit the growth of new shoots, cause defoliation, and induce bituminous coal disease. Occurs in multiple generations in one year.
The prevention and control is mainly based on pesticide control, and the peach aphid has occurred after flowering but has not caused leaf rolling. The pesticides are imidacloprid, acetamiprid, halodioxapyr, flufenamide, spiromethyl ester, etc., and yellow plates can also be hung in the orchard to trap and kill winged aphids.
Pear heartworms
The pear heartworm mainly eats fruits and shoots. Adults lay eggs on the surface of the peach fruit, one per fruit, and the larvae hatch and bury into the fruit, and feed on the kernel or under the skin, and the feces remain in the fruit.
The control can be carried out together with the peach aphid, using chlorantraniliprole, cyantraniliprole, acetamiprid, cyfluthrin, etc. If insect fruits are found in peach orchards, they should be removed in time and buried deep or burned.
Peach borer
Peach borer is also called peach borer, peach spot borer, an important fruit borer pest. The larvae are eaten into the fruit for feeding, and the damaged fruit is full of insect feces, which is easy to cause fruit cracking and rot, which seriously affects the quality and yield.
Prevention and control can be installed in the orchard to trap sexual traps, insecticidal lamps to kill adults, can also be bagged after the peach fruit grows to the size of a thumb and the second natural fruit drop to prevent moths from laying eggs on the fruit surface. In the adult stage and oviposition period, imidacloprid, pyrethamide, chlorantraniliprole or acetamiprid are used for spraying.
longicorn
The larvae eat the cortex and xylem of the peach branches, weakening the tree, shortening its lifespan, and dying in patches in severe cases.
The control can be carried out manually during the adult occurrence period in June. Before the adults lay eggs, the branches of the peach tree are coated with white coating to prevent the adults from laying eggs; the pesticides are used to spray green Weilei microcapsules, thiamethoprid, etc., on the trunk to kill the adults, or use a syringe to inject phenoxycarb, chloramidophos and other poisons to kill the larvae.
Precautions
Do not spray pesticides during the flowering period of peach trees to protect bees and improve pollination and fruit set; avoid using copper pesticides such as Bordeaux liquid to avoid serious perforation of leaves and a large number of defoliations; add an appropriate amount of neutral laundry detergent or dish soap to the liquid medicine to increase the adhesion of the liquid medicine and improve the control effect.
