The present invention relates to methods and uses for combating or controlling invertebrate pests in turf, which comprises applying a mixture comprising alpha-cypermethrin and dinotefuran to the turf area, the invertebrate pests or their food supply, habitat or breeding grounds. The most common invertebrate pests in turf are certain worms, e.g. Armyworm, ants, e.g. fire ants, bugs and in particular white grubs, which are larvae of different kinds of insects, mainly of bugs. They usually live in the soil and damage the turf grass plants by feeding on their roots. The turf pests can be efficiently combated or controlled by the methods and uses of the invention.

Compositions with supramolecular structures for agricultural use include a pesticide, a supramolecular host chemical or a supramolecular guest chemical configured to engage in host-guest chemistry with the pesticide, and a solvent, and methods of preparing the same, are included. Methods of controlling weeds at a crop site include applying an agriculturally effective amount of the composition to the crop site are also included.

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.
