Soybean pods are larvae infestation from June to October every year. Adults have phototaxis. Eggs are produced on tender horns, flowers, and petioles. Newly hatched larvae enter the tender horns or flower feeding, resulting in flowers and horns falling off and invading older larvae. Beans are fed inside the beans, and the beans are often rotted after the rain. The larvae have the habit of nocturnal emission and backlighting. They hide in flower, beans, or leaves during the day and they excrete insect excrement to plug the boreholes. In addition to sporadic activities during the rainy days and daytime, they generally start crawling from the wormhole in the evening. Come out and stop to go out in the early morning of the next day.
Preventive measures to clear the field falling flower falling angle, and remove the wounded leaves and beans to reduce the source of insects. Black lights are set up to use adult phototaxis habits to trap and kill. Pharmaceuticals were selected from 5% Ruijinte 2000x, 40% fenvalerate 6000x, 2.5% deltamethrin 3000x, and sprayed once every 10 days.
Leafminers are larvae that invade into the leaves. They eat only the upper and lower epidermis and form tortuous tunnels that affect plant growth. Leafminers mainly damage peas, beans, cowpeas, cabbages, broccoli, cabbage, rapeseed, radish, lettuce, tomatoes, eggplant, and potatoes.
Prevention and control measures use adult armyworm board to trap adult insects. Adults mainly lay eggs on the back of leaves, and the sprayed liquids should focus on the back of sprayed leaves. At the beginning of the larvae damage, insecticides with both internal absorption and contact toxicity were selected, such as 48% of Le Siben EC 800 to 1000 times, and sprayed continuously for 2 to 3 times.
The spider mites on red bean spider's beans are also known as bean leaf mites. From August to September, it was the peak period. Ye Yu sucked on the young leaves, and when the leaves were damaged, they collapsed and fell easily. In the early stage of development, the leaves lose their green color and become red and white, and the thin wire mesh on the back of the leaf can directly recognize the range and area of ​​occurrence. Immediately after the occurrence, a sprayer was used to spray a pesticide envelop, the extent of which was slightly larger than the range of occurrence, and then the plants in the encirclement were thoroughly sprayed to prevent the spread of red spiders.
Prevention and control measures can be sprayed with 20% compound Liuyangmycin EC 1000 times, 1.8% avermectin EC 1500-2000 times, 15% Dailing EC 3000 times, and 20% EC 2000 times. Rotate medications and promote the use of highly effective, low-toxic biopesticides.
It can be used for surgical operations, patient treatment; epidemic prevention and inspection in public places; disinfection in virus-contaminated areas; and can also be widely used in military, medical, chemical, environmental protection, transportation, epidemic prevention and other field
By setting a protective collar, the neck of the operator can be kept warm and protected. The provision of a hand guard is helpful for the surgical staff to temporarily place their hands in the hand guard while waiting during the operation, which plays a protective role and is more in line with the principles of aseptic operation and occupational protection.
By setting the shrinking cuffs, it is beneficial to make the cuffs fit the wrists, prevent the cuffs from loosening, and prevent the gloves from slipping off during the operation and the operator's hands are exposed to the gloves.
The design of the new humanized protective surgical gown has been improved in the key areas of the gown. The forearm and chest area are double-thickened, and there are handguards in front of the chest and abdomen. By arranging reinforcing sheets (double-layer structure) in key areas, it is beneficial to improve the water-permeability of surgical gowns and improve safety.
