Winged Apple Apple

After the apple was taken out of the bag, small insect eyes often appeared on the fruit surface, which seriously affected the fruit rate and the income of the farmers. Wei Lixin, a senior agronomist at the Agricultural Technology Center of Heyang County, Shaanxi Province, said that this was caused by the damage of the apple leaf roller moth. Wei Lixin said that there are four ways to prevent and control fruit farmers can choose according to their own convenience.

The artificial prevention and cure of scraping old branches and skins and eliminating overwintering insects.

Trapping and killing adult larvae in the orchard using a small apple lure or sweet and sour liquid. The ratio of sweet and sour liquid is sugar: wine: vinegar: water = 1:1:4:16, and 3 to 5 per mu.

Toxic larvae in late July and late August focus on the generation of larvae spraying control. Combining spraying of Prosin Zinc, New Manganese, and Pyraclostrobin to control anthrax leaf blight, a mixture of 2% Mefloxacin 1000 times and 2.5% Meth salt High Chloride 1000 times.

Picking leaves to prevent removal of the bag immediately after removing the fruit around the leaves, both to reduce the larvae feeding fruit, but also conducive to fruit coloring.
