Embodiment 1

[0024] 1. The production method of corn core loss agent: expressed in weight percentage, the original drug is 0.3% parathion and 2% imidacloprid, mixed with 97.7% of the drug carrier, stirred evenly, made into granule agent, and packed according to a certain weight bag.

[0025] The drug carrier is prepared by mixing sand and water with a particle size of 0.1-4 mm in a ratio of 100:2.

[0026] 2. Usage and dosage:

[0027] Apply the pesticide during the big trumpet mouth period of corn growth (the corn grows 7-15 leaves at this time), drop the corn core loss agent into the corn horn mouth, and apply 1 to 2 grams of granules per plant.

Embodiment 2

[0029] 1. The production method of the corn core loss agent: expressed in weight percentage, the original drug is 3% parathion and 0.1% imidacloprid, mixed with 96.9% drug carrier, stirred evenly, made into granule agent, and packed according to a certain weight bag.

[0030] The drug carrier is prepared by mixing sand and water with a particle size of 0.1-4mm in a ratio of 100:10.

[0031] 2. Usage and dosage: Apply the pesticide in the big bell mouth period of corn growth (at this time, the corn grows 7-15 leaves), drop the corn core dropping agent into the corn bell mouth, and apply 2 to 4 grams of granules per plant.

Embodiment 3

[0033] Expressed in percent by weight, the original drug is 1% parathion and 1% imidacloprid, mixed with 98% drug carrier, stirred evenly, formulated into granules, and packed in 2 kg per bag.

[0034] The drug carrier is prepared by mixing sand, water and blue pigment with a particle size of 0.1-4mm in a ratio of 100:7:1.

[0035] Usage and dosage are identical with embodiment one.

Abstract

The invention relates to a compound pesticide for preventing and controlling corn pests, in particular to a novel corn core dropping agent for preventing and controlling corn borers and aphids. The core-losing agent contains the original drug and the drug carrier, expressed in weight percentage, the original drug is a mixture of 0.3-3% insecticide and 0.1-2% imidacloprid, and the balance is the drug carrier. The novel corn core-losing agent of the present invention can be sprayed at one time, and can control various corn pests such as aphids and corn borers at the same time. It is simple and easy to operate, saves labor and medicine, has high work efficiency and good effect.

Description

1. Technical field: [0001] The invention relates to a compound pesticide for preventing and controlling corn pests, in particular to a corn core dropping agent for preventing and controlling corn borers and aphids. 2. Background technology: [0002] The corn borer, commonly known as the borer, belongs to the family Lepidoptera. Corn borer is an important pest in maize production, which poses a serious threat to maize production and has become an important factor affecting the high and stable yield of maize. According to statistics, the corn borer can reduce the yield of corn by more than 8% in light occurrence years, 10% to 15% in moderate occurrence years, and more than 30% in heavy occurrence years. Since corn borer is difficult to control and control, seeking more effective control methods has always been a problem that people continue to discuss. [0003] Because corn borer is a major agricultural pest in the world and poses a great threat to corn production, countries...
