Problems solved by technology

[0004] It is not difficult to see from the above that at present, the main purpose of the corn rough dwarf disease is to prevent it. Once the corn is infected with the virus, there is no good way to eliminate the virus. Usually: for the corn in the seedling stage, the diseased plants are eradicated and re-sowed, which can be used later. The sown corn and the normal growing corn have different development times, and they cannot pollinate each other, resulting in a low seed-setting rate and reduced yield; for the corn that has headed and flowered, there is nothing to do; for the heavy field, replant red sweet potato, vegetables and other crops

Embodiment 1

[0011] Present embodiment 1: the present invention contains 10% gibberellin A3 soluble wettable powder and 3.95% Sclerotinia triazole·copper·alkanol·zinc wettable powder; above-mentioned composition thing is mixed by the weight ratio of 1: 45. That is, get 1 gram of 10% gibberellin A3 soluble wettable powder (produced by Sheyang County Chemical Plant, Jiangsu Province), 45 grams of 3.95% triazole Sclerotinia Copper Alkanol Zinc wettable powder (Xi'an Hailang Chemical Industry Co., Ltd. Company production) and mix well. When in use, when preventing corn rough dwarf disease, add 15 kilograms of water to the above-mentioned prepared medicament, to 667m 2 The two-leaf one-core corn field can be sprayed to prevent the occurrence of rough dwarf disease of corn; when the corn is infected with rough dwarf disease, add 12 kg of the above-mentioned prepared medicament to the 667m 2 Spray in the corn field, and then spray again every 6-7 days (it can also be sprayed for the third time i...

Embodiment 2

[0012] Embodiment 2: the present invention contains 10% gibberellin A3 soluble wettable powder, 3.95% Sclerotinia triazole · copper · alkanol · zinc wettable powder and 10% imidacloprid (produced by Jiangsu Funing County Pesticide Factory) . The weight ratio of 10% gibberellin A3 soluble wettable powder, 3.95% Sclerotinia triazole·copper·alkanol·zinc wettable powder and 10% imidacloprid is 1:40:20. That is, take 1 gram of 10% gibberellin A3 soluble wettable powder, 40 grams of 3.95% Sclerotinia triazole-copper-alkanol-zinc wettable powder, and 20 grams of 10% imidacloprid and mix evenly. Using method is the same as embodiment 1.

Embodiment 3

[0013] Embodiment 3: the present invention contains 10% gibberellin A3 soluble wettable powder, 3.95% Sclerotinia triazole · copper · alkanol · zinc wettable powder and foliar fertilizer (one produced by Shandong Qingzhou Luyuanquan Organic Fertilizer Factory) spray green). The weight ratio of 10% gibberellin A3 soluble wettable powder, 3.95% Sclerotinia triazole·copper·alkanol·zinc wettable powder and foliage fertilizer is 1:50:45. That is, get 1 gram of 10% gibberellin A3 soluble wettable powder, 50 grams of 3.95% Sclerotinia triazole-copper-alkanol-zinc wettable powder, and 45 grams of foliar fertilizer and mix evenly. Using method is the same as embodiment 1.

Description

Technical field [0001] The invention relates to a pesticide, in particular to a new pesticide for preventing and treating corn rough dwarf disease. Background technique [0002] Maize rough dwarf disease is a corn virus disease caused by maize rough dwarf virus (MRDV), which belongs to the plant reovirus group and is a double-stranded RNA spherical virus with a double-layer capsid. Persistent mode propagation. The leaves of corn plants infected with MRDV are wide and short and stiff, the leaves are dark green, the internodes are thick and short, and the top leaves are clustered like Clivia. The rough feeling of the plant, the plant is severely dwarfed, the tassel is degenerated, the ear is deformed, and in severe cases, it cannot bear fruit. Corn rough dwarf was first popular in European countries such as Italy, Switzerland, Spain, France and Yugoslavia. In the early 1960s, corn rough dwarf disease occurred in large areas in Shanghai, Zhejiang, Jiangsu, and Baoding, Hebei...
