Seed treatment composition containing pyridine quinazoline

Abstract

The invention discloses a seed treatment composition containing pyridine quinazoline. The effect component of the composition is a ternary combination of phenamacril, fludioxonil and pyridine quinazoline. The composition has a remarkable synergistic effect, the use effect is improved, the prevention and treatment spectrum is expanded, stress tolerance is induced, and the yield is increased.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to the combination of cyclostrobin, fludioxonil and pyridinequinazoline and the application thereof. [0002] technical background [0003] 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 5-1...

Problems solved by technology

[0003] 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

Cyclostrobin, fludioxonil, and pyridylquinazoline have different action mechanisms, and their control spectrums are not the same. Single-dose use is prone to produce drug resistance, and the dosage is increasing, and the control spectrum is narrow, which cannot meet the actual needs. Arbitrary binary mixtures of acrostrobin, fludioxonil, and pyridylquinazoline also have similar problems to single agent use alone, although they have been improved, so to a certain extent, there is an urgent need for the emergence of new compound agrochemicals
