Embodiment 1

[0024] Embodiment 1: A kind of antibacterial and desinsection corn composite granule, expressed by weight percentage, the ratio of the original drug is shown in Table 1, namely carbendazim 0.1%, mancozeb 3.0%, ethephon 0.5%, compound nitrophenol Sodium 3.0%, imidacloprid 1.0%, phoxim 3.0%, and the balance is auxiliary materials.

[0025] The auxiliary material is an auxiliary agent and a drug carrier, the weight ratio of the auxiliary agent to the original drug is 1:1.2, and the auxiliary agent is a mixture formed by a pull-off powder, a binder and a diffusing agent in a weight ratio of 1:2:2; the pull-off powder It is sodium butylnaphthalene sulfate, the binder is polyvinylpyrrolidone (PVP), and the diffusing agent is sodium methylenedimethylnaphthalenesulfonate.

[0026] The drug carrier is sand, water, and pigment mixed in a weight ratio of 100:2:0.3, and the particle size of the sand is 0.5~2.5mm.

[0027] Preparation method: when preparing, firstly mix the auxiliary agen...

Embodiment 2

[0028] Embodiment 2: the proportioning of the former medicine is shown in Table 1, and the difference with embodiment 1 is:

[0029] In the excipients, the weight ratio of auxiliary agent and original drug is 1:1, the weight ratio of pull-off powder, binder, and diffusing agent is 3:2:3; the weight ratio of drug carrier sand, water, and pigment is 100:4: 0.5.

Embodiment 3

[0030] Embodiment 3: the proportioning of the former medicine is shown in Table 1, and the difference with embodiment 1 is:

[0031] The weight ratio of the auxiliary agent and the original drug in the excipient is 1.5:1, the weight ratio of the pulling powder, the binder, and the diffusing agent is 2:2:1; the weight ratio of the drug carrier sand, water, and the pigment is 100:3: 0.5.

Abstract

The invention relates to multifunctional corn composite granules, which comprise the following raw materials in percentage by weight: 0.1 to 3.0 percent of carbendazol, 0.1 to 3.0 percent of mancozeb, 0.5 to 3.5 percent of ethephon, 0.1 to 3.0 percent of compound sodium nitrophenolate, 1.0 to 3.5 percent of imidacloprid, 0.5 to 3.0 percent of phoxim or monosultap and the balance of auxiliary materials. Bactericide, pesticide and growth adjustor are compounded in the granules to integrate pest removal, pathogenic bacteria prevention and control and growth adjustment, and the granules are applied at one time and can simultaneously prevent and control multiple pests and pathogenic bacteria of corn; and the total prevention and control rate of the granules on the corn pests reaches over 90 percent, and the average yield increase range of the corn is 25 to 35 percent. the granules have broad spectrum, high efficiency, low toxicity, good compatibility, complementary effect and long acting time, can ensure that the corn is not harmed by the pests such as stem borers, aphids and the like during the whole corn growth period by early application, and thoroughly solve the problem of difficult prevention and control of plant diseases and insect pests in the medium and later stages of the corn growth.

Description

technical field [0001] The invention relates to a compound pesticide for corn, in particular to a multifunctional corn compound granule capable of antibacterial, insecticidal and growth-regulating corn. Background technique [0002] At present, the existing corn pesticides have a single function, and need to be used separately for diseases or insect pests in different periods, and need to be sprayed or controlled multiple times. It is relatively easy to apply medicine at the seedling stage, and it is easy to apply and control; but in the middle and late stages of corn growth, the environment of high temperature, rainy and high humidity is conducive to the reproduction of pests and germs, resulting in a large number of pests and diseases. The main pests of corn such as spider mites Pests such as worms, aphids, stem borers, and midges all appeared in large numbers, and diseases such as powdery mildew, smut, rust, and leaf spot of corn also occurred continuously. If these inse...
