Tetramycin compound and application thereof

Abstract

The invention relates to the field of research and development of biological pesticide preparations, and particularly relates to a tetramycin compound and application thereof, which are a divisional application of an invention named 'tetramycin compound and application' having an application number of 2013106143470 and being applied on November 26, 2013. The tetramycin compound comprises tetramycin and an active substance, wherein the active substance belongs to amide, including one or more of benzamides, dicarboximides, formamides, kresoxim-methyl, N-halogenated methylthio-dicarboximides and dimethomorph. Compared with the prior art, the tetramycin compound and application thereof have the advantages that the risk of resistant fungal strain selectivity can be reduced, the service life of the active substance can be prolonged, the prevention and treatment range can be enlarged, the disease prevention effect can be improved, the drug resistance of pathogenic bacteria can be retarded or overcome, the cost can be reduced, and the number of pesticide application times can be reduced.

Description

[0001] The application of the present invention is a divisional application with the application number 2013106143470, the application date is November 26, 2013, and the invention name is "tetramycin compound and its application". technical field

[0002] The invention relates to the field of research and development of biopesticide preparations, in particular to tetramycin complexes and their applications. Background technique

[0003] At present, there are many kinds of pesticides used for plant protection. It is a good thing that there are many kinds of pesticides, but it also brings many problems. Pesticides mostly treat one insect for one treatment, and one drug for one treatment. Therefore, pesticides can only control one pest or disease, and have no effect on other poisons or diseases, and even cause production reduction accidents. No grain harvest. This kind of plant protection technology of treating one insect, one medicine and one medicine is no longer suitable fo...

Examples

example 5

[0065] Example one tetramycin and procymidone compound

[0066] Wherein, procymidone is selected as the active material component. Procymidone is a systemic fungicide, which has special effects on Botrytis and Sclerotinia fungi, can prevent gray mold and sclerotinia of fruit trees and vegetable crops, and is also effective on fungi that are resistant to benzoimazole . After use, the protective effect is good, the duration of effect is long, and it can prevent the development and spread of lesions.

[0067] The embodiment of the present invention adopts the method combining indoor virulence determination and field test. First, through the indoor toxicity test, the synergistic ratio (SR) of the two agents after compounding in a certain proportion is clarified. SR1.5 is a synergistic effect. On this basis, field experiments were carried out.

[0068] After the effective inhibitory concentration range of each drug was determined by pre-test, five doses were set up according to...

[0091] Example tetramycin and azoxystrobin complex

[0092] Among them, the active material component selects azoxystrobin

Embodiment 2-1

[0093] Example 2-1 Preparation method: 18% tetramycin · azoxystrobin EC:

[0094] Weigh 6% tetramycin, 12% azoxystrobin, 4% Nongru 500# (calcium dodecylbenzenesulfonate), 3% Span-60# (sorbitan monostearate), 3% Nongru 2201#, 2% triphenyl phosphite, xylene added to 100%. After the above raw materials are mixed, they are fully dissolved and mixed to obtain 18% tetramycin·azoxystrobin emulsifiable concentrate.
