Seed treatment composition containing pyridine quinazoline and metalaxyl-M as well as trifloxystrobin

Abstract

The invention discloses a seed treatment composition containing pyridine quinazoline and metalaxyl-M as well as trifloxystrobin. An active ingredient of the composition consists of the metalaxyl-M, the trifloxystrobin and the pyridine quinazoline; and the weight ratio of the metalaxyl-M to the trifloxystrobin to the pyridine quinazoline in the composition is (1-10):(1-10):(1-60). The seed treatment composition disclosed by the invention can be prepared into a seed treatment suspension agent, a suspended seed coating agent, a seed treatment microcapsule suspension agent, a dry seed mixing agentand seed treatment dispersible powder. The seed treatment composition disclosed by the invention has the benefits that a significant synergistic effect is realized, the use effect is improved, a control spectrum is enlarged, the stress resistance is induced, and the yield is improved.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to the combination of metalaxyl, trifloxystrobin and pyridinequinazoline and its application. Background technique [0002] There are many kinds of diseases and pests that affect the normal growth of seeds and / or the roots, branches and leaves of the plants grown from the seeds. The application of seed treatment agrochemicals is to protect the seeds and / or the roots, branches and leaves of the plants grown from the seeds. One of the most effective chemical means of protecting leaves from pests and pathogens; using new pesticides without cross-resistance to protect seeds and / or the roots, branches and leaves of plants grown from such seeds from pests and pathogens It is a good solution to reduce the harm; however, currently developing a new pesticide requires screening tens of thousands of compounds, costing US$120-150 million, and a development cycle of 5-10 years. It ...

[0002] There are many types of pests and diseases that affect the normal growth of roots, branches and leaves of seeds and / or plants grown from the seeds. The application of seed treatment agrochemicals is to protect the roots, branches and leaves of the seeds and / or plants grown from the seeds. One of the most effective chemical means of protecting leaves from pests and pathogens; the use of new pesticides without cross-resistance to protect the roots, branches and leaves of seeds and / or plants grown from the seeds from pests and pathogens The harm is a good solution; however, at present, the development of a new pesticide needs to screen tens of thousands of compounds, costing 120-150 million US dollars, and the development cycle is 5-10 years, it is difficult to catch up with the speed of resistance of pests and diseases; Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in the actual operation process

Metalaxyl, trifloxystrobin and pyridine quinazoline have different action mechanisms and different control spectrums. Single-dose use is prone to produce drug resistance. The dosage is increasing, and the control spectrum is narrow, which cannot meet the actual needs. Oxime The binary mixture of strytostrobin and mefenaxyl also has the same problems as the single agent alone, although it has been improved, so to a certain extent, there is an urgent need for the emergence of new compound agrochemicals
