Problems solved by technology

Traditional pesticide application methods, such as root irrigation, poisonous soil mixing, and pouring, etc., usually result in pesticide loss and decomposition rates of 60%-90% due to wind, sun, and rain, and are repeated due to short duration. Medication, resulting in huge waste of pesticides, pollution of the ecological environment and potential threats to human health

preparation Embodiment 1

[0021] Weigh 5.5 kg of talcum powder as the wrapping material, weigh 0.5 kg of chitosan oligosaccharide, and 1 kg of fipronil, mix them into a disc wrapping machine, and heat with hot air. Keep the temperature at 80°C and spray 50% urea-formaldehyde resin aqueous solution intermittently through the spray gun to the core of the pesticide while rotating, and sprinkle the wrapping material on the core of the pesticide while spraying until the wrapping material is used up and dried. When it is lower than 4%, the temperature drops to about 65°C, slowly pour in the paraffin wax that has been melted into liquid in advance, stop heating, keep the equipment to continue to rotate, and the chip temperature drops to room temperature. Weigh, obtain 8 kilograms and contain oligochitosan and fipronil granule mixture.

preparation Embodiment 2

[0023] Weigh 3 kg of kaolin as the wrapping material, grind the ingredients, weigh 0.5 kg of chitosan oligosaccharide, 0.5 kg of fipronil, and 0.5 kg of abamectin, mix and grind them, put them into a disc wrapping machine, and heat them with hot air. Keep the temperature at 80°C. Spray molten sulfur intermittently through the spray gun to the core of the pesticide while rotating, sprinkle the wrapping material on the core of the pesticide while spraying, until the wrapping material is used up, the temperature drops to about 65°C, slowly Pour the polyethylene-heavy oil that has been melted into liquid in advance to seal, stop heating, keep the equipment to continue to rotate, and the temperature of the sheet can be lowered to room temperature. Sieve, weigh, obtain 5 kilograms of chitosan oligosaccharides, fipronil and abamectin microcapsule mixture.

preparation Embodiment 3

[0025] Weigh 2.6 kg of diatomaceous earth as the wrapping material, weigh 0.4 kg of chitosan oligosaccharide, 0.5 kg of fipronil, and 1 kg of chlorpyrifos into a disc wrapping machine, and heat with hot air. Keep the temperature at 80°C. Spray the molten polybutene intermittently through the spray gun to the pesticide core while rotating, and sprinkle the wrapping material on the pesticide core while spraying until the wrapping material is used up and the temperature drops to about 65°C. , slowly pour the paraffin wax that has been melted into a liquid in advance to seal, stop heating, keep the equipment to continue to rotate, and the temperature of the film drops to room temperature. Weigh, obtain 5 kilograms of chitosan oligosaccharides, fipronil and chlorpyrifos granule mixture.

Abstract

The invention relates to an agricultural composition containing chitosan oligosaccharide and fipronil, the agricultural composition is characterized by also containing one or a plurality of component from an insecticidal component, a sterilization component, a plant growth regulator and a fertilizer component, the insecticidal component is selected from one or a plurality of component of abamectin, chlorpyrifos, fosthiazate, thiamethoxam, phoxim, spinosad, isazofos, ivermectin, profenofos, thiodicarb and imidacloprid, the sterilization component is selected from one or a plurality of component of ethylicin, azoxystrobin, fludioxonil, hymexazol, difenoconazole and propiconazole, the plant growth regulator is selected from one or a plurality of component of mepiquat chloride, naphthylacetic acid, chlormequat chloride, uniconazole, paclobutrazol and indolebutyric acid, and the fertilizer component is selected from one or a plurality of component of nitrogen, phosphorus, potassium, calcium, magnesium, boron, zinc and amino acids. The agricultural composition can be one of a granule agent, a microcapsule agent, an absorbent product, a water agent, a water emulsion agent, a suspending agent, a water dispersible granule agent, a wettable powder agent and a microemulsion agent, and is used for root irrigation, sprinkling and pouring, furrow application pesticide-clay mixture or hole application, and the agricultural composition is used for the control of plant diseases and insect pests and regulation of plant growth.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to the agricultural composition containing chitosan oligosaccharide and fipronil and its application in soil diseases and insect pests and plant growth regulation. Background technique [0002] Plant diseases and insect pests have always been one of the main factors affecting agricultural production. Fungi, bacteria, nematodes and maggots are more difficult to control. [0003] Soil pests and diseases of plants have always been one of the main factors affecting agricultural production. Fungi, bacteria, nematodes and maggots are more difficult to control. Traditional pesticide application methods, such as root irrigation, poisonous soil mixing, pouring and other methods, usually result in pesticide loss and decomposition rates of 60%-90% due to wind, sun, and rain, and are repeated due to short duration. The use of pesticides has caused huge waste of pesticides, pollution of the ecologica...
