It includes three types: bacterial shot hole, mildew spot shot hole, and brown spot shot hole. Among them, bacterial shot hole is the most common and is widely distributed in peach-producing regions across the country. Infection of peach trees by this disease can cause a large number of leaves to develop holes and drop off, branches and shoot tips to die, severely weakening tree vigor, affecting flower bud differentiation, and causing huge losses. In addition to harming peach trees, the three types of shot hole disease also harm stone fruit trees such as plum, apricot, and cherry. [Symptoms] Detailed

Identification and Control Methods for the Carambola Fruit Borer Moth
The carambola fruit borer moth is commonly known as the red-line worm. Its larvae occur in large numbers during the flowering period and invade the small flowers to feed on the stamens. The peak occurrence period is usually from late June to early August, and the damage is most severe in extremely hot weather. All the damaged small flowers drop off, often causing crop failure. During the summer full-bloom period, trichlorfon 1000x solution can be sprayed continuously every 5 to 7 days to kill the pests.
