When summer arrives, the temperature gradually rises. The people’s vegetables in their own small courtyard and farmland are far from green, and they look closely at it. Look for it carefully and find no insects. What is this? Why?
It turned out that it was a kind of agricultural pest that clamored to eat the clam dish.
Hey, that is, the scorpion worm that the peasant said, its body length is spindle-shaped, smooth and soft, and it is 30-60 mm long when crawling; it is dark brown, grayish red or yellow-white. One to two generations a year, adult or larvae overwinter in wet roots of the plant roots, from May to July in the field a large number of activities damage.
As a result, many people go out to eat at night and in the early morning, and hide in the soil or under the cover during the day. Normally, it will be unearthed around 6 pm, peaking at 10:10 pm and diving into subterranean or hidden areas before dawn. Temperature 11.5 °C -18.5 °C, soil moisture content of 20% -30% of the best development of the wild pheasant.
Foraging habits are more miscellaneous and mainly damage vegetable seedlings, young leaves and tender stems. The leaves are eaten as holes or nicks, biting off the stems and growing points, so that the entire crop is withered, often resulting in the lack of seedlings and broken ridges. At the same time, excretion of feces, secretion of mucus contaminated vegetables, causing decay, reduce quality.
So, how to prevent warts?
First of all, we can use mulching to reduce the damage; weeds in the fields and fields, weeds are reduced, weeds are reduced, weeds are kept on the edges of the ground and the ditch; seedlings are preserved in the deep trenches during the rainy season, and cultivation is done in small high ridges to keep the surface of the soil dry and inhibiting damage; Weeds are piled up freshly, and weeds are collected and manually captured before dawn.
In addition, during the growth of vegetables, 5–7.5 kg of lime per acre is sprayed on the surface to prevent the entry of cockroaches; during the clam occurrence period, 1% salt water is sprayed on the front face and back wall of the greenhouse to make the body water. Outflow causes death.
Finally, if none of the above methods can be controlled, 6% of MICRO-Slacticide granules (500 g) or 250-500 g of worms may be used per acre after sowing or planting of vegetables. In sunny evenings, uniform application or slicing may be used. Spreading (30-50 centimeters apart) on the bare surface or around the crop rhizosphere, the catfish were killed by the touch and died, which increased the seedling preservation effect and was used once per growing season.
