Detailed Guide to Greenhouse Pepper Pest Control

Due to years of continuous cropping, pepper seedlings suffer from a relatively high incidence of pests. The main pests are mole crickets and aphids. The control situation is described as follows: (1) Mole crickets: the species is the African mole cricket, whose density can sometimes reach 3 per sq m; they mainly bite and feed on sown seeds and seedlings. If no control is carried out, they can eat all the seeds and seedlings in an entire bed, or loosen the surface soil by burrowing, causing the vegetable seedlings to wither and die from water loss. After sowing, apply 3% Miral granular formulation to control them, at a rate of about 2.3-2.5 g per sq m. After application, cover with soil, water, and cover with film. On the 2nd to 4th days, lift the film in the bed furrows each day to manually catch the half-dead mole crickets; the control efficacy can reach over 95%. (2) Aphids: generally occur in small numbers from late March to April, and can be controlled with 10% imidacloprid 4000-fold solution together with other diseases.
