The invention discloses a visual detection method for fruit and vegetable pesticide residues based on a colorimetric array sensor of a smart phone. The preparation method comprises the following specific steps: (1) preparing six types of silver nanoparticles with multifunctional surfaces by taking AgNO3 as a silver source, PVP (Polyvinyl Pyrrolidone), CTAB (Cetyltrimethyl Ammonium Bromide), Tween 80, branched polyethyleneimine, thiomalic acid and L-cysteine as surface modifiers and NaBH4 as a reducing agent and adopting a chemical reduction method; (2) silver nanoparticles are combined with gelatin, and a silver nanoparticle hydrogel patch is prepared; and 3) integrating a smart phone, and constructing a silver nanoparticle colorimetric array intelligent sensor with 1 * 6 sensing element points for visual detection and distinguishing of various pesticide residues on the surfaces of fruits and vegetables. The detection limits of the sensor on cyromazine, chlorpyrifos, imidacloprid, dichlorvos, mancozeb and cartap are 4.9 mg / L, 0.99 mg / L, 0.49 mg / L, 2 mg / L, 3 mg / L and 0.3 mg / L respectively. The method disclosed by the invention has the characteristics of low cost, high sensitivity, strong selectivity, intelligence, portability and the like, and can be used for synchronously detecting and distinguishing various analytes.

The present invention relates to a method o f combating and / or controlling a pest selected from the Lepidoptera order, which comprises applying to said pest, to a locus of said pest, to a plant susceptible to attack by said pest, or to a plant propagation material susceptible to attack by said pest, a pesticidal composition comprising isocycloseram as active ingredient A, and cartap as active ingredient B.

The application discloses a kind of containing prothioconazole, carboxin, cartap pesticide composition and its application, comprising effective component prothioconazole, carboxin and cartap, wherein, with fungicidal activity prothioconazole, carboxin and with nematocidal activity cartap mass ratio is 1~15:1~15:1~10.The pesticide composition of the application effective component mechanism is different, no cross resistance, good physical and chemical compatibility, registration development is feasible, expands the control spectrum, synergistic effect is remarkable, can effectively control rice seedling disease bacteria to carbendazim, prochloraz and acypetacs and other fungicides resistance, cultivate strong seedling, with significant application value to improve the yield and quality of rice.In the prevention and treatment of rice seedling disease, rice seedling disease, rice seedling disease and rice dry tip nematode disease effect is excellent and synergistic effect is obvious, simultaneously promote root strong seedling effect is remarkable, reduce drug synergistic effect, quality is good and cheap, to environment friendly safety, market prospect is broad.

The present disclosures present an insecticidal composition comprising a combination of active ingredients, Emamectin benzoate, Cypermethrin and Cartap hydrochloride, and methods of preparing and using such compositions. The present disclosure aims to provide enhanced control of a variety of insect pests affecting crops, with a synergistic effect that improves efficacy compared to individual components.

The invention relates to the technical field of temperature control, in particular to a temperature grading control method and system for cartap preparation, and the method comprises the steps: collecting the temperature of each measurement point of each height layer at different moments in each control period under a second temperature control stage in real time; calculating the cooperation coefficient of any two measurement points at each moment, and determining the cooperation difference degree of each measurement point at each moment; obtaining an overheat moment, and determining an overheat random value of each measurement point in each control period; and the judgment coefficient of each control period is obtained, the temperature rise rate of each control period is corrected, the corrected temperature rise rate corresponding to each control period is obtained, and the temperature of the alcoholysis reaction kettle is regulated and controlled in real time. According to the method, the temperature rise rate is regulated in real time, so that the regulation accuracy of the temperature in the alcoholysis reaction kettle is improved, unnecessary by-products caused by local overheating are avoided, and the product quality and yield of cartap are improved.

The present invention relates to an agrochemical insecticidal mixture comprising a combination of a nereistoxin analogue insecticide and a further insecticide; and a method for controlling pests comprising treating an infected crop with an effective amount of the insecticidal mixture. The present invention mainly shows the efficacy of cartap mixtures on cotton boll weevils in cotton crops, thereby reducing plant structural damage and improving plant health. In addition, the present invention demonstrates an unexpected synergistic effect observed for the mixture of cartap and chlorfenapyr of the present invention.

This invention discloses a method for treating wastewater from the production of pyrethroid insecticide, comprising: (1) adjusting the pH to 11-12 and adding sodium thiosulfate solution to react and obtain a reaction solution; (2) adding sulfur to the reaction solution and refluxing the reaction at 100-102°C for a set time to obtain a synthetic solution; (3) evaporating and concentrating the synthetic solution to obtain a concentrated solution, adding activated carbon and heating it to perform solid-liquid separation to obtain a filtrate; (4) cooling and crystallizing the filtrate, separating the crystals to obtain sodium thiosulfate pentahydrate. The wastewater treatment process for pyrethroid insecticide of this invention can directly produce high-value-added, high-quality sodium thiosulfate products, realizing the recycling of materials. No polluting gases are generated during the treatment process, the process is simple, and the treatment cost is low.

The invention discloses a fosthiazate and ethylicin-based rice aphelenchoides besseyi disease environment-friendly treatment agent and a preparation method thereof, the fosthiazate and ethylicin-based rice aphelenchoides besseyi disease environment-friendly treatment agent comprises fosthiazate, ethylicin, an auxiliary agent and powder, the mass ratio of fosthiazate to ethylicin is 30: 1-1: 30, the auxiliary agent is selected from one of a filler, a dispersant, a wetting agent, a penetrant, a film-forming agent and a stabilizer, and the powder is powder. The powder is prepared from prothioconazole, imazalil, cartap and a dispersing agent; through scientific compounding of fosthiazate and ethylicin, the contact killing and systemic absorption effects on aphelenchoides besseyi are remarkably enhanced, meanwhile, the use concentration of the pesticide is reduced, damage to soil microbial communities is reduced, the environmental pressure is effectively relieved, and the prevention and control safety is improved; the photolysis stability and slow release performance of active ingredients are remarkably improved, the pesticide effect lasting time is prolonged, the pesticide application frequency is reduced, the adhesion capacity and permeation efficiency of the pesticide on the surfaces of rice leaves are enhanced through the nanometer silicon carrier, and the pesticide utilization rate is increased.
