Embodiment 1

[0013] Embodiment 1: The ratio of raw materials by weight is: 30 parts of imidacloprid, 10 parts of thiamethoxam, 8 parts of morpholine hydrochloride, 5 parts of zinc element (i.e. 12.5 parts of anhydrous zinc sulfate), 5 parts of dispersant NNO, Wet agent K12 4 parts, brilliant blue 3 parts, inert filler 27.5 parts. According to the production of 100kg samples, weigh them respectively according to the above proportions, and the production steps are as follows:

[0014] (1) Weigh 30kg of imidacloprid, 10kg of thiamethoxam, 8kg of morpholine hydrochloride, 12.5kg of anhydrous zinc sulfate, 5kg of dispersant NNO, 4kg of wetting agent K12, 3kg of brilliant blue, and 27.5kg of bentonite, and mix them in a cone Mix in the machine for 30 min;

[0015] (2) Pass through a jet mill, crush until 95% pass through a 325-mesh sieve;

[0016] (3) Mix in the mixer for another 60 minutes to ensure uniform mixing;

[0017] (4) After passing the test according to the standard, it is packaged...

Abstract

The invention belongs to the field of pesticides, and discloses a medicament composition for preventing a maize rough dwarf disease. The effective ingredients are as follows: 10-40 parts of imidacloprid by weight, 5-15 parts of thiamethoxam by weight, 5-15 parts of moroxydine hydrochloride by weight, and 1.5-5 parts of zinc element by weight. Via the fact that the medicament composition for preventing the maize rough dwarf disease is mixed with seeds, the medicament with a strong systemic property is transmitted to each tissue of maize through the germination of seeds. The insects with a sucking mouthpart, such as plant hoppers and aphids, are prevented from invading the maize, so that a medium for spreading virus diseases is blocked. The moroxydine hydrochloride and the zinc element can play a role in preventing and treating the virus diseases. Due to the prophase seed dressing treatment, the times of spraying an insecticide by a farm worker are reduced, the labor and the cost are saved, and moreover, the pollution is decreased. Meanwhile, owing to the capability of improving the germination percentage of the maize, promoting the growth of the maize, causing the steams and the leaves of the maize to keep thickly green, enhancing the premunition of the maize, and increasing the yield, the medicament composition for preventing the maize rough dwarf disease has an abroad application prospect. The dosage form of the medicament composition for preventing the maize rough dwarf disease is low in cost and convenience in manufacture and use, as wettable powder.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a medicinal composition for preventing corn rough dwarf disease. Background technique [0002] Maize rough dwarf disease is a corn virus disease caused by maize rough dwarf virus (MRDV), which is a double-stranded RNA spherical virus with a double-layer capsid and is persistently transmitted by the small planthopper. Maize rough dwarf is an important disease prevalent in the maize production areas in northern my country. It is a devastating viral disease. Once it occurs, it is difficult to cure. It will cause the height of the diseased plants to be less than half of the healthy plants, and most of them will not be able to head and produce fruit. Although individual tassels can be drawn out, there are very few branches and no pollen. The ears are deformed, the tassels are degenerated, and the ears are deformed. In severe cases, they cannot bear fruit, and the yield reduction rate reaches ...
