Pests of Prunus mume and their control

Prunus mume and leaf-feeding pests

For the prevention and control of leaf-eating pests, different drugs should be selected according to the growth stage of Prunus mume and the specific type of pests. Among them, the most common leaf-eating pests are the yellow thorn moth and the big bagworm moth. The best time for effective prevention and control is when the larvae are in their early stages. During this period, 1600 IU/mg Bt wettable powder can be used for spraying at 1000 to 1200 times of solution, which can completely kill the pests and effectively protect the environment. In addition, you can also use nicotine spray, carbendazim spray, or rice suspension spray.

Prunus mume and aphids

For the prevention and control of aphids, chemical control methods are mostly used, such as spraying 3000 to 4000 times diluted 6% imidacloprid emulsifiable concentrate, 5000 to 10000 times diluted 5% acetamiprid emulsifiable concentrate, 800 to 1000 times diluted 1.2% bitter tobacco emulsifiable concentrate, or 800 to 1000 times diluted 50% cypermethrin emulsifiable concentrate.

Prunus mume and fruit borer

For the prevention and control of borer, it can be combined with the trapping and killing of other pests. The specific methods include physical and chemical methods. Physical control methods include installing frequency-vibrating insecticidal lamps to lure and kill adult insects; cutting off insect-infested branches to eliminate overwintering insects; hanging insect traps to lure and kill male adults. Chemical control methods include spraying 1000 to 1500 times diluted Bt wettable powder with a content of 16000 IU/mg, or 1000 to 1500 times diluted 50% cypermethrin emulsifiable concentrate for control.
