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.
