Problems solved by technology

Medicinal fertilizers require the active ingredients of pesticides to be stable in the fertilizer carrier, and require the labor of pesticide application and fertilization to be combined. In traditional planting, pesticide application and fertilization are two separate field labors, which are intensive and costly.
[0003] There are problems such as easy decomposition of pesticides and easy loss of fertilizers when ordinary medicinal fertilizers are applied to the soil. How to make the pesticides in the medicinal fertilizers stable and the fertilizers long-lasting, and to meet the pest control and nutritional needs of crops throughout the growth period through one application, and become a scientific and technological worker. The main direction of research

Embodiment 1

[0016] Example 1 : Thiamethoxam sustained-release microcapsule powder preparation

[0017] Weigh 10g of the original drug of thiamethoxam at room temperature and dissolve it in an appropriate amount of cyclohexanone. After the dissolution is complete, add 15g of MDI in turn, and stir completely to form an organic phase. Weigh 15g of Nongru 600# and dissolve it in 150g of water, add an appropriate amount of silicone defoamer, and stir evenly to form the water phase. Under high-speed shearing, add the oil phase into the water phase until the particle size of the formed 0 / W emulsion is 3-5 μm, stop shearing, transfer the emulsion to a three-necked flask, stir at 500 rpm, and then add 80 mL of 5 % diethylenetriamine aqueous solution was added dropwise to the flask in batches within 1.5h, the system was heated, and kept at 60°C for 3h, then the heating was stopped, and when the temperature returned to room temperature, the prepared thiophene The chlorpyrin microcapsule suspension...

Embodiment 2

[0018] Example 2: Preparation of Thiamethoxam Slow-release Fertilizer

[0019] In the disc granulator, spray the binder on the surface of the fertilizer granules, then add thiamethoxam microcapsule powder, other auxiliary materials, and kaolin; mix and granulate to prepare thiamethoxam microcapsule fertilizer granules.

Embodiment 3

[0020] Example 3: Effects of different types of binders and their dosages on the molding quality of medicinal fertilizers

[0021] Preparation method: In a disc granulator, spray the binder on the surface of fertilizer granules, then add 0.5% thiamethoxam microcapsule powder, the rest of the auxiliary materials, kaolin; mix and granulate to prepare thiamethoxam microcapsule fertilizer granules.

[0022] The composition of the granular fertilizer (mass percentage): 18% of urea, 16% of monoammonium phosphate, and 11% of potassium chloride.

Abstract

The invention belongs to the technical field of fertilizers, and relates to a pesticide fertilizer for delaying pesticide release and application thereof. The invention discloses a pesticide fertilizer for delaying pesticide release. The pesticide fertilizer is characterized by comprising the following components in percentage by weight: 0.01-5% of thiamethoxam, 1-5% of polyglutamic acid, 0.5-10%of sustained-release material, 15-60% of NPK fertilizer, 0.1-2% of binder and the balance of kaolin complementing the percentage to 100%. The pesticide fertilizer for delaying pesticide release can beused for preventing and controlling sugarcane pests; and especially, the pesticide fertilizer has an excellent prevention and treatment effect on sugarcane cotton aphids.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a medicinal fertilizer for delaying the release of pesticides and an application thereof. Background technique [0002] Medicinal fertilizer refers to pesticide fertilizer, fertilizer synergist and other filler substances, which are compounded and processed according to the nutrient ratio required by different crops for different periods of growth. Medicinal fertilizers require the active ingredients of pesticides to be stable in the fertilizer carrier, and require that the labor of pesticide application and fertilization can be combined. In traditional planting, pesticide application and fertilization are two separate field labors, which are intensive and costly. [0003] There are problems such as easy decomposition of pesticides and easy loss of fertilizers when ordinary medicinal fertilizers are applied to the soil. How to make the pesticides in the medicinal ...
