The invention relates to the technical field of novel pesticide application, in particular to an application method and device of a sustained and controlled release pesticide. Analyzing the inhibition degree of the pest species reproduction activity scale on the plant species growth rate through the application area chart, and estimating and analyzing the application dosage based on the inhibition degree to obtain the target application dosage of the sustained and controlled release pesticide required by each application area in the application area chart; constructing a current trajectory decision-making tree, predicting and fitting a propagation activity prediction area of insect pest species in the multi-dimensional space field by using the current trajectory decision-making tree, and screening application point locations of the propagation activity prediction area according to a sustained and controlled release action range of a sustained and controlled release pesticide preset monomer dosage to obtain accurate application point locations; and formulating a reasonable application time point of the sustained and controlled release pesticide through a hot spot distribution density-time frame kurtosis trend model. According to the invention, the application of the sustained and controlled release pesticide can be precisely and reasonably planned and optimized, so that the pesticide effect quality of the sustained and controlled release pesticide on insect pests is improved, and the sustained and controlled release application error is reduced.

The present invention belongs to the field of biological control of agricultural pests, and specifically relates to a functional release medium for predatory mites, a preparation method thereof, and a usage method. The functional release medium for predatory mites includes entomogenous fungi, silica, diatomaceous earth, and fillers. Among them, the entomogenous fungi and diatomaceous earth can control various harmful mites and pests and have no negative impact on predatory mites. The use of this release medium can not only improve the control effect of predatory mites, but also have a certain control effect on other pests such as aphids and thrips, which can broaden the control target range of the original predatory mite products and achieve the integrated control of various harmful mites and pests. In addition, the usage method of this release medium is simple. The functional release medium for predatory mites can not only ensure the application dosage requirements of biocontrol microorganisms, but also reduce the number of field pesticide applications, while improving the control efficiency and effect, reducing the control cost.

The application provides a method for applying two pesticides in a rice-fish integrated breeding mode, carries out evaluation on death toxicity of flutriafol and flusilazole combined exposure to zebra fish, and through research on an application interval, it is proposed that an interval should exist between the application of the two pesticides, the application dose of flutriafol is 5.1-8.5 g (effective component) / mu, the application dose of flusilazole is 4-5 g (effective component) / mu, and the interval is more than 2 days. Preferably, when flusilazole is applied after flutriafol, the interval is 6 days; when flutriafol is applied after flusilazole, the interval is 4 days. The application suggests that the flutriafol and flusilazole mixture should be used carefully in agricultural production, and the interval must be strictly implemented when applied, so as to reduce the adverse effects on the ecological environment, and provide an important scientific basis for monitoring and early warning of farmland environmental pollution and remediation.

The present application relates to the technical field of new pesticide application, in particular to a kind of application method and device of slow-release pesticide.The application area map is analyzed to the degree of inhibition of the growth rate of plant species by the breeding activity of pest species, the target application dose of slow-release pesticide required by each application area in the application area map is obtained based on the degree of inhibition estimation analysis application dose;Current trajectory decision tree is constructed, and the breeding activity prediction area of pest species in multidimensional space field is predicted and fitted using current trajectory decision tree, the application point of breeding activity prediction area is screened by the slow-release effect range of slow-release pesticide preset monomer dose, to obtain accurate application point;The reasonable application time point of slow-release pesticide is formulated by the kurtosis trend model of hotspot distribution density-time frame.The present application can accurately and reasonably plan and optimize the application of slow-release pesticide to improve the efficacy of slow-release pesticide on pests and reduce the slow-release application error.
