Leaf blight, bacterial spot disease, anthracnose and other infestation of leaves and stems can be controlled by Bordeaux wave or 400-fold solution of ethyl iodophos. Sclerotinia sclerotiorum can be sprayed with 1000 times of methyl topiramate. 1000 times omethoate EC can be used to control aphids and night thieves. Blight, also known as stem rot, mainly harms stems and roots. After the pathogen invaded the base of the stem, it formed a light brown spot, which was watery and constricted and rotted, which often caused the plant to die. When the air humidity is high, white filaments can grow in the disease spot. Control methods: A. strengthen cultivation management, avoid continuous cropping, pull out diseased plants and burn them in time, reduce the source of infectious bacteria and reduce the incidence of disease. 2-3 weeks before planting, disinfect the soil with formalin, spray the soil with 30ml water 50 times, then cover the soil with plastic film, remove the cover 5 days later, after 1-2 weeks, wait for the flavor to dissipate before use. B. Chemical control in the early stage of the disease, 40% ethanophosphate aluminum wettable powder 300 times solution can be used to spray control, or 50% carbendazim wettable powder 800 solution can be used to irrigate the rhizome of the plant, with 4L. Seedling rot is a serious seedling disease, which can occur from seed germination to the whole seedling stage. The stem or root of the seedling near the soil surface began to show water stains, then gradually became brown well constriction, and in severe cases, the disease rotted, so that the whole plant lodged or withered and withered. Prevention and control methods: A. the watering amount should be controlled at the seedling stage, and the soil should not be too wet; sowing in time to avoid the influence of uncomfortable temperature; seedlings should not be planted too densely, and time seedlings; keep greenhouse ventilation, light transmission, reduce the temperature between plants, control the disease conditions. In addition, 70% pentachloronitrobenzene powder can be used to disinfect the soil, mix it with an appropriate amount of fine sand and then apply it at the dosage of 5g / m ~ 2. B. Chemical control. In the early stage of the disease, 50% carbendazim wettable powder 800-1000-fold solution was timely sprayed on the tender stems of seedlings and the surrounding soil, or 800-1000-fold chlorothalonil wettable powder could be sprayed. Rust mainly harms the leaves, tender stems and calyx of goldfish grass. The disease of the leaf showed a yellow-green blister spot, then gradually expanded, the blister spot ruptured and exposed a pile of reddish-brown summer spores, and the leaf tissue around the spot became light yellow. The symptoms in the tender stem and calyx are similar to those in the leaves. The growth of the damaged plants was weak, and when the leaves were serious, the leaves were scorched. Prevention and control methods: A. diseased leaves should be removed and burned in time to prevent spread; pay attention to ventilation and light transmission, plants should not be planted too dense; b. Chemical control. At the initial stage of the disease, 15% verapamil wettable powder 200 times, or 65% Dysen zinc wettable powder 400 times. Leaf blight mainly occurs in leaves and stems. When the leaf is infected, the leaf tip or leaf edge begins to produce water-stained spots, then becomes pale, and gradually expands into round or irregular brown spots, with brown irregular rims in the center of the spot, and many small black spots scattered. The infected young leaves are twisted, and in severe cases, the leaves wrinkle and die, hanging from the stem without falling off. Stem disease spot long strip or around the stem, waterlogged, slightly sunken, the center gray-white, the edge of black-brown, the disease often occurs dry crack, and many small black spots, sometimes arranged as concentric ribs. The damage to the stem at the seedling stage often causes seedling lodging. Control methods: A. strengthen cultivation management, remove diseased leaves or diseased plants and burn them in time, in order to reduce the source of primary infection; greenhouse should pay attention to ventilation, plants should not be too dense, not partial application of nitrogen fertilizer. B. Chemical control. At the initial stage of the disease, Bordeaux solution or 65% Dyson zinc wettable powder 600 times the solution can be sprayed. Botrytis cinerea can harm the stems, leaves and flowers of plants, mainly flowers. Germs invade through weak host tissue. Leaf damage often occurs at the tip or edge of the leaf at first. At the initial stage of the disease, watery spots appear in the disease, and then gradually expand, and the diseased tissue becomes dark brown and rotten. After the pathogen invades, it can also cause the infection of pedicel and stem and produce ulcer spot. When the disease spot surrounds the pedicel or stem, it can cause the flower ear to wither. Under moist conditions, the damaged parts are covered by grayish-brown mildew layer and often produce small black granular sclerotia. Control methods: A. timely removal of diseased flowers, diseased leaves, and concentrated burning, in order to reduce the source of infection. Greenhouse should strengthen ventilation, watering should not be too much, control indoor temperature and humidity. Rational application of nitrogen fertilizer and appropriate application of phosphorus and potassium fertilizer can improve the disease resistance of the plant. In the process of flower management, try to avoid causing wounds to plants and reduce the chance of bacterial infection. B. Chemical control. At the initial stage of the disease, 70% methyl topiramate wettable powder 800 / 1000 times liquid or 50% carbendazim wettable powder 800 / 1000 times liquid spray can be used for prevention and treatment. Spray once a week, 2 times in a row. Aphids usually concentrate on tender buds, leaves and twigs to suck juice, causing plant damage parts to atrophy and deformation. aphids also secrete honeydew to pollute plants and cause soot disease and other diseases. It can be sprayed and killed with 800 times liquid of Wanling 600 times or 800 times diluted by 25% ivy, or 800 times of 1000 times with 40% EC. Quick culling is a broad-spectrum organophosphorus scale insecticide with contact, stomach poison and strong penetration, can infiltrate into plant tissue, and has a good control effect on chewable and piercing mouthparts pests. It is sprayed once a week for 2 times in a row, and has a special effect on shell insects and aphids. Red spiders often stab and suck leaf juice on the back of the leaves, causing the leaves to change color or even curl. It can be sprayed with 1000 times of water with 40% dicofol. Whitefly ingestion of plant juices can cause leaves to fade, curl and shrink, and often become a medium for the transmission of various toxins. Can be sprayed with 0.01% solution that the enemy kills. Thrips feed on young buds, young leaves, flowers and young fruits on plants as adults or nymphs. The tender leaves are curled after being eaten, and the buds and flowers are damaged and withered at the initial stage, which can be sprayed with 25% ivy or 40% dimethoate 400 times 500 times.
