Problems solved by technology

However, due to the weak contact property of this type of medicament, there is no fumigation effect; and the dosage is small and the duration of effect is long, so it is easy for the pests to develop resistance; in addition, this type of medicament is mainly powder, emulsifiable oil or microemulsion at present, which is not very good. suitable for sugarcane crops
[0006] Organophosphorus insecticides, such as valaxon and diazinon, belong to medium and low toxicity insecticides, which have contact killing, stomach poisoning and fumigation effects, but the systemic effect is not strong; and oxime Thion and diazinon have a short duration in soil, and the control effect on subterranean pests is not ideal

Embodiment 1

[0050] Granule preparation (by weight percentage):

[0051] Thiamethoxam 0.8%, oximephos 1.2%, diesel oil 1%, polyvinyl alcohol 0.4%, and the rest is quartz sand (fineness: 0.85-2.00mm). The components are stirred and mixed evenly to make granules.

[0052] The usage method of the mixture is as follows: it is applied to the sugarcane planting ditch during the next planting stage of the sugarcane, and the dosage is 60-80 g / mu of active ingredients.

[0053] Table 2 is the control effect of the mixture on sugarcane borer. It can be seen from Table 2 that the mixture of thiamethoxam and oximathion at a ratio of 0.8:1.2 has excellent control effect on sugarcane borers, and the control effect of 60-80g of active ingredients per mu reaches 91.35-97.30%, which is obviously better than that of the control agent. Control efficacy of fenthion and carbofuran.

Embodiment 2

[0055] Granule preparation (by weight percentage):

[0056] Thiamethoxam technical 0.5%, diazinon technical 1.5%, diesel oil 1%, polyvinyl alcohol 0.4%, the rest is quartz sand (fineness 0.85-2.00mm), each component is stirred and mixed evenly to make Granules.

[0057] The use method of the mixed preparation is as follows: the sugarcane is applied to the sugarcane planting ditch during the next planting period, and the dosage is 40-80 g / mu of active ingredients.

[0058] Table 3 is the test effect of this mixture on sugarcane black cane turtle. The data shows that the control effect of the compound agent on sugarcane black cane turtle with 40g and 80g of active ingredients per mu reaches 75.10% and 84.65% respectively, which is better than the effect of the contrast agent carbofuran.

[0059] Table 4 is the control test effect of the mixture on sugarcane borer. The results show that the control effect on sugarcane borer is 69.06-81.77% when 40-80 g of active ingredients ar...

Embodiment 3

[0061] Granule preparation (by weight percentage):

[0062] 0.5% of imidacloprid technical material, 8.5% of oximephos technical material, 0.3% of lauryl azone, 1% of paraffin wax, and the rest is quartz sand (fineness: 0.85-2.00mm). Each component is stirred and mixed evenly to prepare Granules.

[0063] The usage method of the mixed preparation is as follows: the sugarcane is applied to the sugarcane planting ditch during the next planting period, and the dosage is 120-150 g / mu of active ingredients.

[0064] Table 5 is the experimental effect of the compounding agent on sugarcane brown beetle larvae (grubs). The data shows that the control effect of the mixture on grubs with 120g and 150g of active ingredients per mu reaches 70.59% and 77.38%, respectively, which is better than that of the control agents terbufos and carbofuran. However, the effect of 90g / mu of active ingredient is only 66.81%, and its control effect is slightly better than that of the contrast agent.

Abstract

The invention relates to a pesticide production and preparation technology, in particular to a sugarcane insecticide. The invention provides a sugarcane insecticide containing a neonicotinoid insecticide, which is prepared into granules or water dispersible granules by mixing the following components in percentage by weight: 0.1-10% of neonicotinoid insecticide, 0.2-15% of organophosphorus insecticide and the balance of assistants, wherein the neonicotinoid insecticide is one of or mixture of any two of thiamethoxam, imidacloprid and thiacloprid; and the organophosphorus insecticide is one or mixture of phoxim and diazinon. When the sugarcane insecticide of the invention is used for preventing and treating sugarcane pests, the sugarcane insecticide has contact poisoning and stomach poisoning functions, has a good systemic conduction function and has a good function of controlling underground and aboveground pests of sugarcane; the sugarcane insecticide which has broad-spectrum insecticidal effects has good effects on preventing and treating sugarcane borers, underground insects, thrips, woolly aphids and the like; the sugarcane insecticide which has a long lasting period can be applied once to effectively eliminate the harm of sugarcane borers in the seedling stage, underground insects, thrips and the like; and the sugarcane insecticide has smaller lethality to natural enemies. The sugarcane insecticide of the invention is used as an important substitute for highly toxic pesticides, has the advantages of low toxicity, high efficiency, safety to people and livestock and is environmental friendly.

Description

technical field [0001] The invention relates to pesticide production and preparation technology, in particular to sugarcane pesticides. Background technique [0002] At present, most of the pesticides commonly used in sugarcane are highly toxic and high residue insecticides, such as terbufos, carbofuran, phorate, isofenphos-methyl, etc. The use of such pesticides can easily cause human and animal poisoning and death accidents. After long-term and large-scale use, it will indiscriminately kill non-target organisms, causing serious damage to the ecological environment of farmland. The residue and accumulation of pesticides and their metabolites cause damage to agricultural products. Environmental pollution and other issues directly or indirectly threaten human survival and health. Therefore, in recent years, the Ministry of Agriculture of my country has issued a series of policies and measures on restricting and prohibiting the use of highly toxic and high residue pesticides,...
