Farmers reacted recently. White powder was found on the leaves of the planted oil and wheat dish, and the yellowish-brown lesions appeared under the powder. I do not know the cause. Through field observation, it was a disease of downy mildew. Oil-wheat downy mildew is the main disease in the production of oil and wheat in the current protected area. The incidence rate is high, the general diseased plant rate is 30%-55%, and the diseased plant rate in severe plots reaches 80%-100%. Most of the leaves are dead due to disease, leading to Can not eat, directly affect the quality and production of oil wheat, causing losses to farmers. Symptoms: Oil and wheat downy mildew mainly damage the leaves, from the seedling stage to adult plants can be the disease, the emergence of white mold layer on the back of the diseased leaves, after the yellow withered; Adult disease, the disease from the bottom of the leaves, appeared on the leaves Light yellow near-round or polygonal lesions, when the damp leaves grow white powder on the back, and sometimes can be spread to the front of the leaves; late lesions turn into yellow-brown and connect into pieces, and finally the whole leaf dry. Sometimes germs can infect the stem and cause the stem to darken. Cause of the disease: The bacteria on the field strains can also be transmitted to the newly planted oil and wheat dish for initial infection. Overcast and rainy, the air is damp, and more dew is conducive to the formation, germination and infection of the disease. Low-lying land plots, soil-viscosity or over-grained planting, watering, extensive field management, poor air and light transmission, heavy smashing, and high-level nitrogen fertilizers are all conducive to disease occurrence. Control methods: Available 58% metalaxyl manganese zinc 1000 times + agricultural energy 750 times liquid or 57% enolase zinc 750 times + Jin Tailong top dressing 600 times or 72% frost urea manganese zinc 800 times Liquid + effluent 750 times liquid alternately using the king, 5-7 days spray once, severe spraying can be 3-5 days once, can effectively control. As the general resistance to downy mildew has increased in recent years and the above usage effects are not good, 50% dimethomorph may be used, 58% metalaxyl manganese zinc or 1000.8% or 66.8% Prostomoxime 800 times or 68.7% fluorine phycoferrate 800 times, alternating use, can effectively control the occurrence.
