Solanaceous vegetables must be protected against tea

Tea yellow pods, also known as young leafhoppers, side food crickets, complex feeding, mainly damage the tea tree. In recent years, the damage to vegetable crops has become increasingly serious, mainly affecting eggplants, peppers, tomatoes, potatoes, and also crops and flowers such as cucumbers and legumes. Adult crickets and young cubs can all be harmed. Most of them are concentrated in young leaves. Eggplant and pepper are the most serious victims. As the corpus callosum is small and difficult to detect with the naked eye, the symptoms of the disease are sometimes similar to viral diseases, and some vegetable farmers mistakenly prevent and treat the virus, resulting in poor results and serious losses.

Disease symptoms

The symptom of tea damage caused by tea scutellaria is often confused with virus disease and misdiagnosed. Viral diseases are mainly transmitted by maggots, and they can also be transmitted through the seeds, which are poisonous and mechanically rubbed. The diseases can be caused all year round in protected vegetables. The damaged plants are first slightly chlorotic in the leaf veins of the heart, but not obvious. The leaf is gradually reduced to the leaf shrinkage, and later the diseased leaves are thickened to form the "buckle" and "down buckle". The tender stems are distorted and have a willow leaf shape. It is not noticeable to the naked eye but can be observed under a magnifying glass.

Habits

Tawny tea has tenderness, and when the feeding site becomes old, it immediately shifts to the new young site. Chengyu and Ruoqiang are feeding on the back of the young tender buds and young leaves, causing chlorosis of the leaves. Tea scutellariae occur mainly in warm areas, with the most severe occurrence of vegetables in greenhouses. Multiple generations can occur in one year, and one generation can be completed in 4-5 days at about 30°C, and one generation can be completed in about 7-10 days at about 20°C. It can occur throughout the year in the greenhouse. In mid-March, it began to occur in the greenhouse. The period from mid-June to late July was the peak period. The exposure period was slightly later.

Control methods

Agricultural control choose healthy and unblemished seedlings planted, timely tillage and weeding, remove litter, reduce the number of insects.

Pharmaceutical control seize early spraying control. May use 2000% of 73% Kotel Emulsion, 2000 times of 15% Broom Emulsion, 2000 times of 5% thione ketone Emulsion, 1000 times of 50% Emulsion of bromoxanthone, or 25% of Efficacy The quizphos-containing EC 800 times, or the 35% SAC 1000 times, or the 20% chloramphenicol 3000 times, or the nebulizer 3000 times evenly sprayed. The above medicines can be alternately used in turn, sprayed once every 7-10 days, and sprayed 2-3 times. It should be noted that spraying is stopped 10 days before harvesting. In the shed when the central point of injury occurs when the medication, spraying the focus is on the upper part of the plant, especially on the back of the young leaves and tender stems.
