Some of the dead leaves of amaranth are caused by epidemics and gray molds, some of them are caused by pests and other physiological diseases, etc. Therefore, the prevention and treatment of amaranth leaves must be analyzed.
The epidemic disease is the main disease of the leeks in the protected areas. Water-stained lesions were found on the affected parts. The leaves and scapes were dark green, while the roots and bulbs were light brown. The diseased parts had no obvious edges. The diseased part produces a white sparse moldy layer when it is wet, and the diseased leaf turns to a dry yellow color when it is dry. The soft rot of the infected plant's roots and stems cannot normally absorb water and nutrients, resulting in the overlying or dry parts of the ground. The occurrence of the disease is related to drainage. During the prevention and treatment, attention should be paid to drainage and dehumidification. In the early stage of disease, 25% of thioredox may be used 600 times, or 58% of metalaxyl MnZn may be 500 times, or 40% of BDP 200-300 times. Liquid, 72% Preclosure 1200 times, 72% Kelu wettable powder 600 times, 40-50 kg per acre, spraying every 7-10 days.
The incidence of gray mold began with the tip of the blade developing downwards, and white or pale brown spots appeared on the front and back of the blade at the onset of the disease. As the disease progresses, the lesion expands into a fusiform or elliptical shape, and finally the lesion is contiguous and the diseased leaf is dry. When wet, the diseased leaves produce a layer of gray to grayish green dense mold. In addition to prevention and control of drainage and dehumidification, the spray method can be used in the initial stage of disease, before spraying, soil sprayed before each harvest, alternate spraying 50% carbendazim or 70% thiophanate-methyl WP 500 times, necessary It can be used 50% fast-king or 50% acetaminophen and 50% nellikon wettable powder 1000 to 1500 times, alternately, every 7 days, continuous control 2 to 3 times.
Root leeks are simply called quail, and adults are called larvae. The larvae gather on the non-vegetated underground stalks and tender stems, causing damage and rot. The shoots and leaves on the ground turn yellow and die. Generally, there are three major damage periods each year, from early April to late May, early June to mid-July, early July to late October, of which the third is the most hazardous. Prevention and control measures: In the adult emergence period, use 2.5% green kaempferol or 2.5% enemies or 20% cypermethrin 3000 times solution, spray evenly from 9 to 10 in the morning, once in 10 days, and even spray 3 ~ 4 times. Kill adults and reduce spawning numbers. When the pesticides were sprayed and applied, the tip of the leek was yellowed. When the plants were scattered, every 667 m2 was sprayed with 200-250 ml of water, 200-250 ml of water, and 1000 kg of water. 5 days effective, effective period of 25 to 30 days. With irrigation water, apply 667 square meters of 48% of Bass 300-500 ml to the right amount of water to make mother liquor, and then slowly inject into the water stream at the inlet, so that it is poured into the root of leeks with the water stream.
Physiological diseases of leek dry tip, leaf dry, dead plant phenomenon, and sometimes with soil acidification, ammonia poisoning, high temperature and low temperatures caused by white tip rotten leaves, calcium deficiency, lack of boron, manganese surplus will also cause tip yellowing. Take preventive measures in a targeted manner.
