Pay attention to prevention and control of blindness in middle and late cotton
Cotton-lipped stink bugs can cause harm in cotton seedlings and budding bells. It is now in the period of vigorous flowering and flowering of cotton, which is also the main damage period of the blind stink bug. It can cause cotton bud bells to fall off. However, the current transgenic insect-resistant cotton is not resistant to sucking mouthpart pests such as aphids, and once the weather conditions are favorable for blind aphid occurrence, it can easily cause a serious loss of cotton production. Therefore, we must strengthen the prevention and control on the basis of understanding the hazards of the obscurity. Cotton-lipped foals include species such as green-lipped maggots and mid-black-blind plagues, which often occur in mixed forms. They are small and medium-sized insects in the shape of oval, and they have three kinds of eggs, nymphs and adults. The egg is a long, eggplant-shaped egg. It grows on the main veins of the leaves, the edges of the large leaves, the petioles and the bells under the epidermis. With adults, nymphs harm, activity is strong. The top of the cotton, the side of the heart caused damage after perforation of cotton leaves, "broken leaf madness", headless seedlings, long seedlings. After flower buds are damaged, yellow spots appear on bud crowns, anthers shrink, affect fertilization, and cause shedding. After the young bell was injured, water-stained brown round thorn spots appeared on the shell, and then turned into dark brown, the internal ovule was damaged, which affected the development of fibers. In severe cases, the concavity could become a stale or even fall off. Cotton bollworms are multi-hosts and omnivorous pests that, in addition to harming cotton, also harm broad beans, pods, scorpions, soybeans, potatoes, carrots, sunflowers, peppermint, peanuts, alfalfa, comfrey, ramie, wild radish, and red three. Leaves, beets, celery, garland chrysanthemum and other crops and poplar, willow, mulberry, alfalfa and other trees and a variety of weeds. Control of the source of blind-spotted weevil outside the cotton field is crucial to reduce the occurrence and harm of blind stink bugs in cotton fields. Blind stink bugs are often difficult to detect in the early stages of cotton field damage. When the cotton plants are damaged, the prevention and control are too late. Therefore, it is necessary to strengthen the control of insect field and cotton fields based on the monitoring of insect pests, in accordance with the guidance of the local agricultural technology department. Medication. In the seedling stage, there are 4-5 insects, 10-12 buds, and 20-25 harves during the seedling period. They can be treated with Shi Xian, Xin Bao, Rui Jin Te, and phoxim, and pay attention to other pests in the cotton field. Governance. For example, if a uniform spray of 90 ml per mu, or 90 ml of 24% of Xinbao Emulsion, is applied, it can be used to treat blind ticks, corn borers, and cotton bollworms. Organic phosphorus pesticides such as omethoate and phoxim, 2.5% kantrin, and fipronil have also been shown to be effective in the prevention and control of blind ticks. Spraying medicine to use a motorized misting machine is effective, and when using a small-sized manual sprayer, several machines can be used at the same time. The effect of spraying around the cotton field is better. Cotton seedlings should be sprayed together with the control of the host plant, and the spraying should be focused on tender heads, side hearts, and flower buds. Pay attention to safe medication in hot seasons and prohibit the use of highly toxic and highly toxic pesticides. For the multi-headed seedlings that may cause harm to cotton plants, the remedy measures such as leaving two or one strong branch in a timely manner can be used to give full play to the compensating function of the cotton plant, especially the large amount of compensation in the bud, which will increase the number of bolls. Recover some of the losses and minimize the loss of blindness damage.
Size
Because of different growing environment and conditions of itself, the fruit will be different types of shapes and sizes, usually we deliver the size 220/280/320/350 and so on, but can also supply other sizes.
