This invention discloses a herbicidal composition containing propyzoxystrobin and chlorpyrifos, and its application, belonging to the field of pesticide technology. The active ingredients of this herbicidal composition are propyzoxystrobin and chlorpyrifos, with a weight ratio of propyzoxystrobin to chlorpyrifos of 1:5 to 5:1. Through the synergistic effect of the two active ingredients, this herbicidal composition addresses the seed dormancy and germination characteristics and resistance issues of black nightshade in pumpkin fields, achieving a synergistic control effect of "rapid-acting + long-lasting" and "closed + foliar" action. The control efficiency can reach over 80%, with an optimal ratio reaching as high as 93.1%. It also significantly increases pumpkin yield without adversely affecting pumpkin growth, solving the technical problems of the lack of dedicated control agents for black nightshade in pumpkin fields and the strong resistance of conventional agents in existing technologies.

This invention discloses a method for cultivating long-branch Buddha's Hand fruit by cutting branches. The method uses a special variety called "Sunshine" and cultivates high-quality long-branch Buddha's Hand fruit by controlling the density of fruiting branches, spraying a 1500-fold dilution of 3% naphthaleneacetic acid during the bud stage to induce finger-shaped splitting, spraying a gibberellin-chlorpyrifos-potassium dihydrogen phosphate compound solution during fruit development to synergistically thicken the fruit stalk, adjusting the branch direction in summer to keep the fingertips pointing upwards, and combining this with midday shading. This method results in a 26.7% increase in fruit stalk diameter, a 6.4% increase in the number of fruits with open fingers, a 100.2% increase in the number of long-branch fruits, a 20.0% reduction in the number of fruits with fruit surface burns, and an 8.8% reduction in the number of fruits that fall off after harvest. The number of fresh-cut long-branch marketable fruits increases by 100.2%, and the long-branch marketable fruit rate reaches over 70%. Overcoming the bottlenecks of traditional cultivation such as weak fruiting ability of long branches, thin and weak fruit stalks that are easy to fall off, and easy damage to the fruit surface, the cultivated long-branch Buddha's Hand fruit has the advantages of being resistant to fruit drop, having a smooth fruit surface, having a well-developed fruit shape, and having suitable branches. It can be directly used for cut flower scenarios such as vase decoration and bouquet matching, creating a new category of Buddha's Hand cut fruit and significantly enhancing its ornamental and economic value.

This invention provides a high-efficiency seedless grape cultivation technology. Through systematic innovation in seed pretreatment, compound growth regulator formulation, substrate optimization, and precise cultivation management, it overcomes traditional technological bottlenecks. Seed pretreatment employs a quicklime-distilled water activation method combined with wood ash-milk fermentation and ultrasonic-assisted treatment, significantly improving embryo activity and germination rate. The growth regulator is a golden ratio compound of gibberellin and chlorpyrifos, applied to the flower spikes twice, with sodium tungstate added to prolong efficacy, achieving a seedless rate >95% and a 20%-30% increase in berry weight. The substrate uses a multi-stage formulation system, adjusted to pH 5.0-5.5 after low-temperature sterilization, and incorporates 5% biochar to enhance water retention and pollution resistance. Innovative cultivation management includes optimized H-shaped trellis system combined with rain-sheltered cultivation and precise water and fertilizer management, resulting in a stable yield of over 1500 kg / mu, extended shelf life to 15 days, and a cultivation cycle shortened to 2 years before fruiting. This technology comprehensively improves fruit quality and planting efficiency, demonstrating significant application value.

This invention relates to a method for preparing a high-fluorine chlorpyrifos-imidacloprid suspension, belonging to the field of pesticide technology. In preparing this high-fluorine chlorpyrifos-imidacloprid suspension, an synergist is added to form a water-retaining film on the surface of the droplets during residual spraying. This allows the droplets to be evenly dispersed on the object surface, preventing the liquid moisture from evaporating or being absorbed, thus improving the adhesion of the product to the target surface and prolonging its effect. The pesticide adheres to the object surface at a size of less than 5 micrometers. Upon contact with the target organism, a trace amount of penetrant promotes the absorption and activation of the active ingredient, thereby improving the efficacy. The product prepared by this invention is environmentally friendly, highly safe, and has a long-lasting effect on sanitary pests with a high contact kill rate.
