The moth mainly eats pulp and has a high pest rate(4 cell trays bulk). When the moth appears, we can spray 2.5% deltamethrin 5000-8000 times or 20% fenpropathrin 2000-4000 times for control. Or for soil disinfection, generally, vinegar and trichlorfon can be used to make baits and trap moths(2 gallon nursery pots wholesale). Secondly, it is necessary to process the fruits in time after harvesting, and it is not suitable to store them for too long, so as to reduce the spread of pests.

Topdressing was carried out before germination, before flowering, during fruit expansion, during coloring and after harvest(14 gallon nursery pots wholesale). According to the size of mature 3, a ditch with a depth of 50 cm and a width of 20 cm can be opened near the root end (5-year-old trees have a trunk of about 40 cm).

When the big coir moth appears on the dogwood, it can be killed manually. After the leaves fall in winter, the bag hanging on the branch can be picked up by combining with pruning. You can also install black lights to trap and kill moths(15 cell propagation trays wholesale). Spraying control is mainly in the period of insect pest occurrence, spraying 10% fenpropathrin 2000-3000 times or 40% Omethoate 1000 times.
It can also be used for biological control. July is the larval peak period, and 90% trichlorfon 1000 fold solution should be sprayed in time for control(12 cell trays bulk). The adult of leafhoppers sucks the young branches and leaves, which causes the branches to dry up and leaves to fall seriously, which affects the growth of trees(21 cell propagation trays wholesale). The control method is to spray 50% times of 2000 times of phosphamine emulsion or 5000-8000 times of chrysanthemum ester.(11 inch plastic plant pots wholesale indonesia)
