Embodiment 1

[0027] Example 1: See Table 1 for the main components of the corn dwarfing insecticidal agent. Each component is expressed in weight percentage.

[0028] The auxiliary materials include auxiliary agents, fillers and drug carriers. The auxiliary agents are a mixture of pull-off powder, spreading agent, diffusing agent and white carbon black, and the weight ratio of each component is 5:6:4:10.

[0029] The opening powder is sodium butylnaphthalene sulfate, the spreading agent is trisiloxane polyoxyethylene ether, and the diffusing agent is β-naphthalenesulfonic acid formaldehyde condensate. The filler is kaolin, and the ratio of kaolin, additives, chlorpyrifos, imidacloprid, and pirimicarb is 2:1:1.

[0030] The drug carrier is a mixture of medical stone, water and pigment in a ratio of 100:4:0.3, and the particle size of the medical stone is 0.5-2.5mm.

[0031] Preparation method: first mix the additives evenly, add the filler kaolin and stir evenly to obtain a mixture; then m...

Embodiment 2

[0033] Embodiment 2: The main components of the dwarfing corn insecticide and heart-removing agent are shown in Table 1, and the difference with Example 1 is:

[0034] The weight ratio of sodium butylnaphthalene sulfate, trisiloxane polyoxyethylene ether, β-naphthalenesulfonic acid formaldehyde condensate and white carbon black in the auxiliary agent is 3:6:4:9.

[0035]The drug carrier is a mixture of medical stone, water and pigment in a ratio of 100:2:0.02, and the particle size of the medical stone is 0.5-2.5mm.

Embodiment 3

[0036] Embodiment 3: The composition of corn dwarfing insecticide heart-losing agent is shown in Table 1, and the difference with Example 1 is:

[0037] The drug carrier is a mixture composed of medical stone, water and pigment in a ratio of 100:6:0.5, and the particle size of the medical stone is 0.5-2.5mm.

[0038] The weight ratio of sodium butylnaphthalene sulfate, trisiloxane polyoxyethylene ether, β-naphthalenesulfonic acid formaldehyde condensate and white carbon black in the auxiliary agent is 3:2:1:4.

Abstract

The invention relates to a dwarfing and pest-killing corn plant core-removing agent, which comprises the following raw material medicaments in percentage by weight: diethyl aminoethyl hexanoate 0.05-2.5, ethephon or paclobutrazol 0.1-3, chlorpyrifos 0.3-3, imidacloprid 0.01-0.09, pirimor 0.1-2.5 and auxiliary the balance. The medicament can complete pest prevention and control and growth regulation by one time of core-removing medicament application, wherein in one time of core-removing medicament application, various corn pests such as ostrinia nubilalis and aphid are prevented and controlled; the average corn plant height is reduced by 20 to 50 centimeters; the prevention and control rate of the ostrinia nubilalis and core-eating worms is over 80 percent; the prevention and control rateof the aphid is over 95 percent; and the corn yield is increased by more than 20 to 50 percent. The medicament is simple convenient in application, labor-saving, medicament-saving and safe, prevents harm caused by the ostrinia nubilalis and aphid in a whole period of growth of corns and completely solves the problem of pest prevention and control in a post-period of corns, thereby increasing cornyield and harvest, reducing environmental pollution and being worthy to be promoted and used.

Description

1. Technical field: [0001] The invention relates to a compound pesticide for preventing and controlling corn pests, in particular to a core dropping agent capable of dwarfing corn and preventing and controlling various corn pests. 2. Background technology: [0002] Corn borer, commonly known as corn borer, is one of the important pests in the growth of corn. It poses a serious threat to the growth of corn and has become an important factor affecting the stable and high yield of corn. According to the survey, the corn borer can reduce the yield of corn by more than 8% in the year of light occurrence, and even reduce the yield of corn by more than 30% in the year of heavy occurrence. There are many ways to control corn borer, and chemical control is more commonly used, but chemical control generally has the disadvantages of short duration, multiple application of pesticides, high toxicity, and unsafe for humans and animals. Take the 50% parathion emulsifiable concentrate list...
