Netizens who know are also asked to help introduce golden needle worms, commonly known as kowtowing worms, and iron filariasis are the larvae of kowtowing worms. the common species of golden needle worms are golden needle worms, thin-breast golden needle beetles, brown needle worms, and wide-backed golden needle worms. The farming network has sorted out the harm and control methods of golden needles, which are listed in detail below for netizens' reference. The harm of golden needle worm: generally, the harm of adult golden needle worm to crops is very small, but it is very harmful to crops, and it is the main underground pest. Because the wormholes of golden needles are small, they can penetrate into the depths of crops to do harm. Golden needle worm can not only harm the underground root and tuber, but also harm the root and stem of the host. Golden needle worm will damage the root system of crops, resulting in a decrease in absorption function and a reduction in yield. When the harm of golden needle worm is serious, it will not only reduce the quality of crops, but also affect the edible value of crop fruits, and cause crop lack of seedlings and broken ridges, resulting in a substantial reduction in yield, or even no harvest. The occurrence of golden needle worm is more serious in field crops, dry land and wasteland in spring and autumn. The control methods of golden needle insects: first, turning deeply into the ground in autumn or spring, some adults or larvae can be turned to the surface, so that they can freeze to death, air-dry or be preyed on by natural enemies, parasitic and mechanically killed, so as to increase the mortality of pests. Generally, the number of worms can be reduced by 15%, 30%. Method 2. Applying more rotten organic fertilizer can improve soil structure, improve permeability, provide good conditions for microbial activity, promote the robust development of vegetable roots, and enhance the insect resistance of crops. Because in chemical fertilizers, ammonium bicarbonate, ammonium humate, ammonia and other ammonia fertilizers can emit irritating ammonia and have a certain repellent effect on pests. Method 3. During the peak period of adults, 80-1000 times of 90% trichlorfon can be sprayed, or 100-150g of 90% trichlorfon per mu (666.7 square meters), mixed with a small amount of water and mixed with 15-20kg of fine soil to make poisonous soil scattered on the ground, combined with raking to make the poisonous soil mixed with the soil. To kill adults. Method 4. Seed dressing with 50% phoxim EC can kill larvae. The ratio of medicine, water and seed is 1: 50, 50: 600. First mix the medicine with water, then spray the liquid on the seed, stir it evenly, then wrap it with plastic film and sow it for 3-4 hours. Turn it 1-2 times in the middle, wait for the seed to absorb the liquid dry, and then sow. Method 5. If the golden needle worm has been damaged and the quantity of the insect is large, the medicine solution can be used to irrigate the root. Generally use 500 times of 90% trichlorfon, 800 times of 50% phoxim EC, or 800 times of 25% carbaryl wettable powder. 150-250g per plant could kill the rhizosphere larvae. Method 6. In the peak period of adults, every 30000 square meters of vegetable fields, use a 40 watt black light, 30 cm from the ground, set up a basin, put water in the basin and a small amount of kerosene. Turning on the lights at night can induce adults to drown in the water. What is the harm of root-knot nematode? what is the ground tiger?
