The most effective defense

The genus Diptera is a genus of the genus Diptera and the larva of the larva is known as the earthworm. The main damage is leeks, but also onions, onions and garlic. Larvae accumulate in the roots, bulbs, and pseudo-neck of leeks, and they feed mostly from the rhizome or bulb side of leeks, and the affected parts turn brown and rot. The larvae also gnaw on the fibrous roots of the leeks to make them bald. Larvae sometimes inject from the white tender stem near the ground, and then down into the bulbs. Each young stem or bulb often gathers dozens or even dozens of larvae for damage, making the leek leaves yellow, wilting, dry, and even die into a pier, causing great damage to the production of leek.

Occurrence

Planted in open field in south-central part of the province, it took 4-5 generations in one year and overlapped in generations. The larvae hibernate in the 3-4 cm soil or bulbs around the roots of the larvae. Most of the wintering larvae move from late March to mid-May. 1-2 centimeters from the surface of the plague, from early April to mid-May, emerged as adults and copulated spawning, from April to June into the prosperous period, light from July to September, and severely damaged from late September to mid-October. . Shed room leeks can occur all year round. In the winter, they continue to damage the sheds as they enter the sheds. From December to February, they are severely damaged.

Control methods

1. Agricultural control. Before the spring amaranth sprouts, the top soil from the loquat soil is sun-dried and sun dried. After 5-6 days, the larvae can be sun dried. The application of planting wood ash before covering the soil can not only treat the lice but also increase the yield. Frozen water and irrigation in early spring can reduce the damage. After cutting the head knife or cutting two knives, the combination of water and topdressing ammonia can reduce the damage. Shed room leeks in the cover leeks or when transplanting leeks, should choose no bulbs. In adulthood, adult insects were killed by stick insects. The method is to use 40 parts of polypropylene tackifier and 60 parts of engine oil to fully mix, and stir and dissolve in a thermostatic water bath at 30° C. to make sticky shellac, coat the front and back sides of the rubber plate, and the size of the plate can be made by the material. Suitably, generally 40 cm * 30 cm is better, 6-7 pieces per mu is appropriate, set the height of 50-80 cm.

2. Chemical control. The critical period of prevention and control is the adult emergence and early stage of larval infestation. In the adult emergence period, 40% chrysanthemum EC 3000 times, or 50% phoxim 1000 times, or 50% cyromazine 4000 times can be used for spraying. Seriously injure the field. After the first application, apply it once every 10-15 days. In the generation of egg hatching, the highest peak period was 4 kg per mu with 3% mullerill granules, and 5-10 kg of dry fine earth was spread between the rows of leeks and covered with soil. The insecticidal effect was good. In the larvae damage period, with the method of pouring the liquid, the effect is better. Use 200-400 ml of 48% Los Herb cream per acre, use a manual sprayer for 1000 liters of water, remove the spray film, and spray the liquid into the root of leeks along the ridge. 48% of Roche Centaury may also be used first The water is formulated into a mother liquor, which is injected into the water stream when irrigating, so that it is poured into the root of the Chinese leeks with water. This method is simple and labor-saving, but the dosage needs to be appropriately increased. Can also be used to 48% Burnet EC Irrigation root, 300-400 ml per acre, 500 liters of water, with a sprayer or kettle, etc., watering Leek root along the ridge. Can be controlled twice a year, the first time in the spring after the shed, the second time in the autumn before the shed.

The use of methamidophos, parathion, phorate, phosphine, monocrotophos, and other highly toxic and highly toxic pesticides to prevent root rot is strictly prohibited to ensure the safety of vegetables and foods.

Monkeypox is a viral zoonosis (a virus transmitted tothose seen in the past in smallpox patients, typically-presents clinically with fever, rash and swollen lymphnodes and may lead to a range of medical complications.It is caused by the monkeypox virus which belongs totheorthopoxvirus genus of the Poxviridae family.Thereare two clades of monkeypox virus:the West Africanclade and the Congo Basin (Central African) clade.Theoname monkeypoxoriginates from the initial discovery ofthe virus in monkeys in a Danish laboratory in 1958.Thefirst human case was identified in a child in the Demo-cratic Republic of the Congo in 1970.
