Embodiment 1

[0027] Embodiment 1: as figure 1 As shown, according to a preparation method of a medicine-fertilizer mixture for preventing and treating rice borer of the present invention, 0.05%~10% methoxyfenozide original drug, 10%~60% fertilizer, 0.1%~2% slow-release agent, 0.1%~10% binder, 0.1%~0.5% coating agent, and appropriate amount of filler are mixed evenly in a closed mixing tank, then added to the granulation equipment for coating granulation, at 80℃~100℃ Dried until the water content of the granules is less than 3%, and sieved (the particle size range is 2000um to 4000um). After passing the inspection, the required medicine-fertilizer mixture for controlling rice borer can be obtained. The powder sieve is crushed and returned to the mixing tank for reblending. Unqualified products are returned to the mixing tank for re-mixing after inspection and analysis of the reasons. The mixing adopts a step-by-step method. Raw materials with low component content are first mixed with a c...

Embodiment 2

[0032] Embodiment 2: In order to better verify the practical application effect of the present invention, a kind of medicine fertilizer mixture of preventing and treating rice stem borer of the present invention is used for preventing and treating rice stem borer, rice stem borer, rice stem borer below with field drug effect example Efficacy test of Leaf Roller Borer.

[0033] Tables 2 to 4 of the test results show that the active ingredient dosage of 0.08% methoxyfenozide fertilizer mixture is 70-100 g / ha. 0.08% methoxyfenozide drug-fertilizer mixture is more effective than 24% methoxyfenozide suspension concentrate, and the product is safe for all growth stages of rice.

Abstract

The invention discloses a pesticide-fertilizer mixer for controlling rice stem borers and a preparation method of the pesticide-fertilizer mixer. An active ingredient of the pesticide-fertilizer mixer is methoxyfenozide. The pesticide-fertilizer mixer comprises the following components by total weight of the pesticide fertilizer: 0.05%-10% of the methoxyfenozide, 10%-60% of fertilizer, 0.1%-2% of slow-released agent, 0.1%-10% of binder, 0.1%-0.5% of coating agent and the balance of filler. The components are mixed uniformly according to the proportion, granulated by using a coating method and then dried and screened to form the pesticide-fertilizer mixer disclosed by the invention. The pesticide-fertilizer mixer for controlling the rice stem borers can be used for fertilizing and realizing the control on rice leaf folder, chilo suppressalis, tryporyza incertulas and pink rice borer by one-time fertilization in the rice production, therefore, a method of using the pesticide and the fertilizer for two times or more under existing conditions is overcome.

Description

technical field [0001] The invention relates to a medicine-fertilizer mixture for controlling rice stem borers and a preparation method thereof. Background technique [0002] Methoxyfenozide, chemical formula: [0003] [0004] Chemical name: N-tert-butyl-N'-(3-methyl-2-toluoyl)-3,5-dimethylbenzohydrazide, English name: methoxyfenozide, a kind of insect growth regulator. Ecdysteroid insecticide, inhibits feeding. It mainly interferes with the normal growth and development of insects, even if the pests moult and die. [0005] Existing methoxyfenozide application technology, 240 g / liter methoxyfenozide suspension application method is water spraying, methoxyfenozide and fertilizer use are separated. [0006] The inventor has conducted in-depth research on the dosage form and application of methoxyfenozide, combined it with fertilizers to prepare a medicinal fertilizer mixture, and completed the two processes of killing insects and topdressing fertilizers at the same ti...
