Wheat powdery mildew must be prevented

Wheat powdery mildew is one of the major diseases of wheat and it can occur in every growth period, and it is the most serious in heading-maturity. After the onset of wheat, photosynthesis was affected, the number of grains per ear was reduced, and the weight of one thousand grains was decreased. When the wheat was severe, it led to early plant withering, resulting in reduced yields and even no harvest.

Due to climatic reasons, the pre-winter group is small. After turning green wheat, in order to promote the growth of wheat, most of the wheat fields were watered before the jointing of wheat, and there were three consecutive effective precipitations before jointing. After the jointing of wheat, the waterlogging condition was sufficient, and the ineffective little pods retreated slowly, resulting in the formation of closed canopies of wheat fields. The ear layer was irregular and the pods were more. This year, wheat powdery mildew tends to show bias.

First, the disease characteristics Wheat powdery mildew can occur in all parts of wheat, leaf and leaf sheath damage, severe infection can also be infected in the early stages of the disease in the disease to form a yellow spot, gradually forming a nearly round to oval white Powder mildew, powdery mildew conidiophores and conidia; later turned gray, scattered above the small black particles, powdery mildew closed capsule shell.

Second, the regular occurrence of pathogenic bacteria after the winter first spread between the lower leaves of the plant, after the gradual development of the middle and upper leaves, when severe can be developed to the panicle. The optimum temperature for onset is 15°C～20°C, and high density, large water and fertilizer, and continuous rainy weather are favorable to its epidemic. There is a significant difference in resistance between varieties.

Third, the prevention and treatment of wheat powdery mildew prevention and control should be the main prevention, in the selection of disease-resistant varieties and chemical seed dressing on the basis of prevention and control combination, in the absence of disease prevention, or early onset, the use of chemical control effect is more ideal. It can be used to prevent wheat midge insects and wheat aphids, and the active ingredient of triadimefamide is 7-10g/mu, or 50% carbendazim WP 80-100g, or 12.5% ​​WP wettable powder 20-30g. Spray 30 to 50 kg of water for spraying, and pay attention to penetrate the lower leaves of the plant when spraying. Experiments have proved that water consumption is more critical, with the same dose, the same agent water consumption is less than 30 kilograms, and the control effect must be sprayed once every 7-10 days to enhance the control effect.

Foot Warmer is also named as Heating Boot, as it looks like a boot in the shape.

It has a fashionable design, hence it is also a good choice as a promotional gift.

In the cold winter, foot warmer is a best choice for keeping warm. When the feet are warm, the entire human body warms up quickly.

It also has a controller with adjustable heat settings, as well as the auto shut off function.
