Adults and nymphs of cotton mealybugs can damage cotton, especially the nymphs. Adult body and wings have waxy white powder. The nymphs are 5 years old and the 1st instar nymphs can crawl. The nymphs of other ages are fixed on the back of the leaves. This worm can develop for about 10 generations a year. It begins to enter the cotton seedlings in May. The most suitable temperature is 20~30°C. The peak period of damage is from August to September. When the temperature is appropriate in the middle and early October, it can still continue. Harm. In the early stage of the damage of cotton aphid, only the cotton leaves were latent on the surface, and then the middle and lower leaves of the cotton plants were all damaged, especially the leaves of the upper part. According to the investigation of a cotton field that was seriously damaged by the cotton plantation in Jidong City, Hanchuan City, there were 50 to 60 heads of adults and nymphs in the upper leaves, and there were between 2000 and 3,000 heads of cotton per plant, and as many as 4000 to 5,000 heads. After the sap of the victim's leaf is sucked, faded spots or reddish-brown spots appear on the leaf surface, and the leaf margins and the entire plant leaves and growing points are shriveled and scorched, resulting in a large amount of shedding of the bells, reducing the boll weight, and reducing the yield of the light by 5 to 10 %, serious reduction of 20 to 30%. This year's weather is conducive to the occurrence of cotton mealybugs and should not be taken lightly. First of all, the competent agricultural departments at all levels must timely issue the dynamics of cotton mealworms, provide yellow warning for prevention and control, and enhance the alertness of grass-roots agro-technicians and cotton farmers in preventing and controlling cotton mealybugs. At the same time, organize farmers to prepare motorized sprayers in advance and carry out group defense measures on re-issued cotton fields. Other light-haired cotton fields should also be treated early. Second, we must thoroughly purify the surrounding environment of cotton fields. In spite of the unfavorable weather conditions in the past year, many vegetable greenhouses near the cotton fields facilitate the hiding of cottonseed meal. Therefore, it is necessary to thoroughly clean the remaining branches in the vegetable greenhouses, remove the weeds from the cotton fields, and reduce the number of weeds as much as possible. source. Third, rapid chemical control. The counterpart to control pesticides, one can use 3% Royal Dan wettable powder, 60 grams per mu; two available 3% Qi Qiao EC 50 ml per mu, respectively, watering 15 to 30 kg spray; three available silver finches (3% acetamiprid Moistenable powder) 1000-2000 times liquid; 4 can be used 20% acetic hydrazone WP 1500 times and 1.8% avermectin EC 3000 times mixed spray; 5 can be used in the early stage of insects 25% Praderaph EC 100 times liquid spray; 6 can be used 10% nitenpyram 2000 times. Full body harness is a form of protective
equipment designed to protect a person, animal, or object from injury or
damage. The harness is an attachment between a stationary and
non-stationary object and is usually fabricated from rope, cable or
webbing and locking hardware. Some safety harnesses are used in
combination with a shock absorber, which is used to regulate
deceleration when the end of the rope is reached. One example would be
bungee jumping. Full Body Harness,Fall Protective Equipment,Safety Harness Lanyard,Safety Wasit Belt Greateagle Safety Products Co., Ltd. , https://www.greateaglesafety.com
