Problems solved by technology

The harm of the disease not only causes serious yield loss, but also greatly affects the quality of wheat
[0003] At present, the prevention and control of wheat diseases is too dependent on a single chemical agent, resulting in the emergence of pathogenic bacteria resistance
For example, the use of triazole fungicides to control wheat powdery mildew is very effective, but studies have shown that the resistance of powdery mildew to triazole fungicides is becoming increasingly prominent, and the problem is very serious

Embodiment 1

[0019] Embodiment 1: take by weighing 5 kilograms of triadimefon, 5 kilograms of thiram former medicine, 90 kilograms of auxiliary agent, wetting agent adopts saponin powder in the auxiliary agent, and its consumption is 5 kilograms, and dispersant selects lignin for use, its consumption It is also 5 kg, the filler is kaolin, the dosage is 80 kg, and then weigh 10 kg of humic acid, all the above materials should be fine powders that can pass through a 30-80 mesh sieve, and use a conical double-helix mixer to After mixing for 45 minutes, the uniformity reaches 95%, which is the finished product of the fungicide for disease prevention and production increase.

Embodiment 2

[0020] Embodiment 2: take by weighing 1 kilogram of triadimefon, 20 kilograms of thiram, 79 kilograms of auxiliary agents, the wetting agent in the auxiliary agent adopts saponin powder, and its consumption is 33 kilograms, and the dispersant is selected lignin, and its consumption It is also 30 kg, the filler is kaolin, the dosage is 16 kg, and 200 kg of humic acid is weighed. All the above materials should be fine powders that can pass through a 30-80 mesh sieve, and they are mixed with a conical double-helix mixer After 40 minutes, the uniformity reaches 96%, which is the finished product of the fungicide for disease prevention and production increase.

Embodiment 3

[0021] Embodiment 3: take by weighing 8 kilograms of triadimefon, 72 kilograms of thiram, 20 kilograms of auxiliary agent, the wetting agent in the auxiliary agent adopts sodium dodecylbenzene sulfonate, and its consumption is 5 kilograms, and the dispersant is selected for use The amount of alkylnaphthalene formaldehyde condensate sulfonate is also 5 kg, the filler is white carbon black, the amount is 10 kg, and 100 kg of humic acid is weighed. All the above materials should be able to pass 50-60 mesh Sieve the fine powder, mix them with conical double-helix mixer for 35 minutes, and the uniformity reaches 98%, which is the finished product of the fungicide for disease prevention and production increase.

Abstract

The disease-preventing and yield-increasing disinfectant consists of thiram, triazolone, assistant and humic acid in certain weight proportion. It is prepared through mixing thiram, triazolone, assistant and humic acid in certain weight proportion. When it is applied, the disease-preventing and yield-increasing disinfectant is compounded into water solution for dressing seed or spraying to foliage. The disease-preventing and yield-increasing disinfectant has broad disease preventing and controlling spectrum, and can decrease harm of dry hot wind and raise the yield and quality of wheat.

Description

technical field [0001] The invention belongs to pesticides, in particular to pesticides used for wheat disease prevention and yield increase, as well as the preparation method and application method of the pesticides. Background technique [0002] my country is dominated by wheat, the sown area and output are second only to rice, ranking second. Because wheat is widely distributed in my country, it is planted in North China, Northwest China, Northeast China and the Yangtze River Basin, and the types of diseases are different in different regions. There are more than 20 kinds of serious ones in our country, and the common ones are sheath blight, take-all, root rot, leaf blight, powdery mildew, rust, head blight, black embryo and smut. The harm of the disease not only causes serious yield loss, but also greatly affects the quality of wheat. [0003] At present, the prevention and control of wheat diseases relies too much on a single agent, resulting in the emergence of patho...
