The invention belongs to the technical field of pesticides and specifically relates to an aryl sulfide containing a benzylamine structure, a synthesis method therefor, and an application thereof. The aryl sulfide is denoted as compound I. Also provided is an agriculturally acceptable salt of the aryl sulfide. The compound represented by formula I shows excellent effects on various harmful organisms, especially spider mites represented by Tetranychus cinnabarinus, Tetranychus urticae, Tetranychus Kanzawai Kishida, Panonychus citri, etc., and can be used for controlling all kinds of harmful mites.

The present invention relates to pesticidal mixtures comprising as active components at least one active compound selected from compounds of formula I, formula Ia, and mixtures thereof and at least one biopesticide II. Furthermore, the present invention relates to seed treatment compositions comprising said mixtures, to methods and uses comprising the application of these mixtures and to seeds comprising the mixtures of the invention or a seed treatment composition thereof.

The invention relates to the use of aqueous compositions comprising polyethylene glycol as the only active ingredient for controlling the infestation by and/or spread of phytophagous insects and/or mites.

The disclosure relates to composite pesticide plugs for delivery of one or more plant protection materials to internal tree tissue of, for example, fruit trees. The composite pesticide plugs generally include a thermoplastic matrix including a low-temperature processable thermoplastic polymer such as polyvinyl acetate, a cellulosic reinforcement, and a plant protection material. The disclosure also relates to methods of preparing the composite pesticide plugs, and methods for delivering a plant protection material to trees. After injection into the tree trunk, the composite pesticide plug can provide a uniform, relatively consistent dose of plant protection material (e.g., pesticides, biopesticides, etc.) to all parts of the tree throughout the growing season, thus reducing waste of material and cost.

The disclosure relates to composite pesticide plugs for delivery of one or more dsRNA plant protection materials to internal tree tissue of, for example, fruit trees. The composite pesticide plugs generally include a cellulosic material, dsRNA (double-stranded RNA) bound to the cellulosic material, and, optionally, a thermoplastic polymer matrix. The disclosure also relates to methods of preparing the composite pesticide plugs, and methods for delivering a dsRNA plant protection material to trees. After injection into the tree trunk, the composite pesticide plug can provide a uniform, relatively consistent dose of dsRNA to all parts of the tree throughout the growing season, thus reducing waste of material and cost.

Disclosed are compounds of Formula 1 or Formula 1′, including all geometric and stereoisomers, N-oxides, and salts thereof,

##STR00001## wherein R.sup.1, R.sup.2, R.sup.3a, R.sup.3b, R.sup.3c, R.sup.3d, R.sup.4, Z and A, respectively, are as defined in the disclosure.
Also disclosed are compositions containing the compounds of Formula 1 or Formula 1′ and methods for controlling an invertebrate pest comprising contacting the invertebrate pest or its environment with a biologically effective amount of a compound or a composition of the disclosure.

A steroidal piperidone derivative, a synthesis method, and a use thereof are provided. The steroidal piperidone derivative has a chemical structure shown in general formula (1) or general formula (2), where R is any one selected from the group consisting of alkyl, phenyl, substituted phenyl, and a heterocycle. In the synthesis method of the steroidal piperidone derivative, dehydroepiandrosterone (DHEA) is used as a basic raw material to prepare the steroidal piperidone derivative of the present disclosure through a series of reactions. A product prepared by the synthesis method has a high yield and is easily separated, and thus the synthesis method is the optimal method for preparing the steroidal piperidone derivative of the present disclosure. The present steroidal piperidone derivative exhibits prominent toxic activity against sucking pests, such as aphids, spider mites, rice planthoppers, and B. tabaci, and can be used for the control of a plant pest. ##STR00001##

The present invention provides a compound having an excellent efficacy for controlling pests. According to the present invention, a compound represented by formula (I) [wherein Q represents a group represented by Q1, or a group represented by Q2 (where • represents a binding site to a benzene ring), E represents a C5-C6 cycloalkenyl group and so on, L represents an oxygen atom or NH, a combination of R.sup.1 and n represents a combination where R.sup.1 represents a hydrogen atom, and n is 1, and so on, and R.sup.2 represents a methyl group and so on] or its N-oxide, or agriculturally acceptable salts thereof has an excellent efficacy for controlling pests.
