Embodiment 1

[0021] Embodiment one: trichlorfon is 95% former medicine: phoxim is 96% former medicine, and its percentage by weight is: trichlorfon 4.5%: phoxim is 1.5%, white carbon black 5%, ammonium sulfate 2%, starch 2%, clay: 85%.

Embodiment 2

[0022] Embodiment two: trichlorfon is 97% former medicine: phoxim is 98% former medicine, and its percentage by weight is: trichlorfon 1.5%: phoxim is 2.0%, white carbon black 5%, calcium chloride 6 %, starch 3%, slag: 82.5%.

Embodiment 3

[0023] Embodiment three: trichlorfon is 96% former medicine: phoxim is 95% former medicine; Its percentage by weight is: trichlorfon 8.0%: phoxim is 7.0%, white carbon black 4%, ammonium sulfate 3% , starch 4%, kaolin: 74%.

[0024] Carrier processing: choose clay or kaolin or diatomite or coal gangue or slag with a sand content of less than 1%; firstly send the above-mentioned carriers that are confirmed and selected into the pulverizer for initial crushing, and the particle size after crushing is controlled at 2- 5cm, then, the carrier after the initial crushing is sent into the dryer, and at the same time, hot air with a temperature of about 150°C is introduced into the dryer 10 minutes in advance, and the carrier material is dried until the moisture is less than 1%, and then sent into the carrier Naturally cool down to normal temperature in the warehouse and put it aside for later use; after accurately weighing trichlorfon technical substance, phoxim technical substance, a...

Abstract

The invention relates to a compound granule or microgranule of trichlorphon and phoxim and a preparation method thereof. The granule or the microgranule comprises the following components in percentage by weight: 1-10 percent of trichlorphon, 1-8 percent of phoxim, 1-8 percent of white carbon black, 1-5 percent of calcium chloride or ammonium sulfate, 2-5 percent of starch or paraffin and 68-86 percent of china clay or kaolin or kieselguhr or coal gangue or slag. For some crops, particularly for the planting of tobaccos, the granule or the microgranule has good settleability, small drift, light environmental pollution, short residual period, convenient application and time and labor saving. The new preparation form has strong complementarity, greatly improves the stability of solid preparations and avoids adverse factors that the trichlorphon is easy to absorb moisture, acidize and decompose, and the phoxim is easy to decompose under light during spraying. The invention has the advantages of cost reduction, toxicity reduction, convenient application and enlargement of prevent and cure spectrum.

Description

technical field [0001] The invention belongs to the technical field of pesticide compound preparation and its preparation method. The invention can be directly used for preventing and controlling the main underground pests (mole crickets, cutworms, needleworms, grubs, etc.) of general crops, especially in the tobacco planting process. When controlling underground pests in the process of tobacco planting, use hole application and then cover soil. Background technique [0002] (a) At present, highly toxic pesticides have caused many problems, especially the poisoning of pesticide applicators and excessive residues of agricultural products. On the other hand, the United Nations Environment Program and the Food and Agriculture Organization of the United Nations formulated the "Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade" in Rotterdam on September 10, 1998 (referred to as " Rotterdam Conventi...
