Embodiment 1

[0022] 1. The production method of the new 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 granules, and packed according to a certain weight into the bag.

[0023] 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.

[0024] 2. Usage and dosage:

[0025] Apply the pesticide during the big horn mouth period of corn growth (the corn grows 7-15 leaves at this time), drop the new corn core loss agent into the horn mouth of the corn, and apply 1-2 grams of granules per plant.

Embodiment 2

[0027] 1. The production method of the new corn core loss agent: expressed in weight percentage, the original drug is 3% parathion and 0.1% imidacloprid, mixed with 96.9% of the drug carrier, stirred evenly, made into granules, and packed according to a certain weight into the bag.

[0028] The drug carrier is prepared by mixing sand and water with a particle size of 0.1-4mm in a ratio of 100:10.

[0029] 2. Usage and dosage: apply the pesticide in the big bell mouth period of corn growth (the corn grows 7-15 leaves at this time), drop the new corn core dropping agent into the corn bell mouth, and apply 2 to 4 grams of granules per plant .

Embodiment 3

[0031] 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.

[0032] 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.

[0033] Usage and dosage are identical with embodiment one.

Abstract

The invention relates to a compounded insecticide for preventing and controlling corn pests; it especially relates to a new kind-removing core from corn for preventing and controlling corn borer and aphid. The new kind-removing core from corn comprises material medicine and medication carrier. The material medicine contains 0.3-3wt% of pesticide, 0.1-2 wt.% of imidacloprid and the rest is medication carrier. By using only one times, the prevent invention of the new kind corn can prepare agricultural chemicals, and can prevent and control various corn pests at the same time such as corn borer and aphid. The abuse has been changed that aphid and corn borer need to be prevented and controlled separately. Times of preparing some agricultural chemicals and labor's intensity have been reduced. Not only it is realized easily and simply, but also work time and agricultural chemicals is saved. Work efficiency is high and effect is remarkable.

Description

1. Technical field: [0001] 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. 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, cou...
