Problems solved by technology

Due to its high toxicity to aquatic organisms such as fish and shrimp, its application is also limited.
[0008] At present, rice insecticides are limited by crop safety and insecticidal spectrum. Using a single insecticide alone cannot completely and effectively control the occurrence of rice insect pests. Moreover, some insecticides have too long duration in the field, Excessive dosage or uneven application will easily produce resistance or cause residual toxicity to current crops or subsequent crops

Embodiment Construction

[0030] The technical solution of the present invention will be further explained in detail below in conjunction with specific examples, but the present invention is not limited thereto.

[0031] 1. Embodiment

[0032] (1) Example 1: The insecticidal composition containing butene-fipronil and chlorpyrifos consists of the following components in mass percentage: chlorpyrifos 28%, butene-fipronil 2%, alkylphenol polyoxygen Vinyl ether 4%, naphthalene sulfonate 3%, thickener 2%, sodium benzoate 0.1%, water balance.

[0033] Add each component in proportion to form a mixed system, and after grinding, make the solid particles in the system reach the 2-3 micron level, and make a water suspension with an active ingredient of 30% by mass.

[0034] (2) Example 2: An insecticidal composition containing butene-fipronil and chlorpyrifos, consisting of the following components in mass percentage: chlorpyrifos 27%, butene-fipronil 3%, EO-PO block Copolymer 3%, naphthalene sulfonate 3%, thi...

Abstract

The invention discloses a parasiticide composite containing butene-fipronil and chlorpyrifos. The parasiticide composite comprises the following effective components of the butene-fipronil and the chlorpyrifos; the parasiticide composite is a water suspending agent; and the mass percentage ratio of the butene-fipronil and the chlorpyrifos is (1-10):(15-50). The water suspending agent parasiticide composite containing the butene-fipronil and the chlorpyrifos has the characteristics of high parasiticide activity, extended parasiticide spectra and high safety; preferably, the mass percentage of the effective components contained in the parasiticide composite is 30%, and the obtained parasiticide composite disclosed by the invention has the advantages of better parasiticide effect and safety.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition aqueous suspension containing butene-fipronil and chlorpyrifos and a preparation method thereof. Background technique [0002] Rice is the main food crop for humans. However, rice pests and diseases have always been an important factor affecting the high quality and high yield of rice. At present, the main pests and diseases are: rice blast, sheath blight, rice leaf roller, rice planthopper and so on. Recently, with the change of cropping system and cultivation management and the reason of weather, the overwintering base of rice planthopper has increased, and the number of generations and numbers of rice leaf rollers have increased. The single use of chemical agents has led to an increase in the population of drug-resistant (resistant) pests; the unrestrained use of highly toxic pesticides, mainly organophosphorus pesticides, has affect...
