In recent years, the occurrence of garlic root maggots has shown a trend of increasing year by year. Root maggot damage can cause garlic yield reduction and has a major impact on garlic quality, with severe damage leading to serious economic losses. Garlic root maggots (larvae) generally gather on garlic roots and...

Control Methods and Technical Key Points for Gray Mold in Greenhouse Chinese Chives
When humidity inside a greenhouse for Chinese chives is high, gray mold is likely to occur. After the disease develops, pale grayish-brown to white spots gradually appear on the leaves from the tip downward, on both the upper and lower surfaces; after expanding, they become elliptical or spindle-shaped lesions and merge with each other into large dead patches. When air humidity is above 85% and the temperature is 15°C~20°C, warm and humid conditions favor the occurrence of this disease.

What are the control methods for wireworms in Chinese chives?
Apply a root drench with 50% phoxim at 1000x dilution, 80% trichlorfon at 1000x dilution, 50% phoxim-cypermethrin emulsifiable concentrate at 4000x dilution, 20% fenvalerate at 300x dilution, or 2.5% deltamethrin at 3000x dilution. Alternatively, before sowing or transplanting, mix the above agents with poisoned bait and broadcast it, or use a seed dressing agent for coating.

What are the methods to prevent lumpy fruit in greenhouse eggplants?
When the temperature in a solar greenhouse is too low, eggplants often develop lumpy fruit. The lumps are mainly concentrated at the front end of the fruit and appear as finger-like protrusions 0.5-1 cm high. When the fruit is broken open, it is found that in the places where the lumps have formed, there is a relatively large gap between the peel and the flesh. Causes: the greenhouse temperature is too low, especially under unusual weather conditions, when for 3 consecutive...
