Problems solved by technology

[0005] As mentioned above, although there have been examples in the prior art about the compounding of metconazole and some fungicides and the compounding of trifloxystrobin and some fungicides to achieve obvious synergies, but there has been no research on metconazole and trifloxystrobin. Composite reports
In addition, the existing pesticide compounding patents mainly only consider the synergistic effect brought about by compounding. However, although the synergistic effect is the more obvious the better, it is not the only factor to consider when using pesticides. In particular, it needs to be considered Yes, the toxicity and environmental pollution of the compounded composition
For example, although some active ingredients are not a big problem when they are used separately, after they are used in combination, the intermediate products produced during their degradation process may undergo adverse chemical reactions and cause environmental pollution problems

Embodiment 1

[0023] Example 1 Indoor Toxicity Determination of Meconazole and Trifloxystrobin Compounded to Wheat Leaf Rust

[0024] 1. Test object: wheat leaf rust fungus collected from the field;

[0025] 2. Test method: Select wheat seedlings at the heading stage with consistent growth, 3 seedlings per pot, and 5 pots of wheat seedlings for testing for each treatment. The prepared 2×105 spores / mL suspension of leaf rust spores was evenly sprayed and inoculated on the wheat seedlings to be tested, and then kept in the greenhouse for 24 hours after inoculation. After 24 hours of inoculation, medicament treatment was carried out, and 5 concentration gradients were set for each medicament, which was sprayed with a test sprayer, about 5mL per pot. After spraying, the wheat was cultivated at about 20°C and relative humidity ≥ 95%. After 7 days, the disease index of the whole plant leaf was investigated according to the classification standard of leaf rust incidence, and the control effect wa...

Embodiment 2

[0038] This embodiment provides a kind of 80% metconazole · trifloxystrobin water-dispersible granule, and its raw material formula is: metconazole 5%, trifloxystrobin 75%, alkylphenol polyoxyethylene phosphate 1%, alkyl sulfate 3%, alkylphenol polyether 3%, gum arabic 2%, diatomaceous earth 4%, bentonite 7%.

[0039] The preparation method of water-dispersible granules is: pre-mixing and re-mixing all materials except gum arabic according to the formula, pulverizing through a jet mill, then transferring to a kneader, adding water and gum arabic to knead, extruding and granulating, and drying to obtain 80 % metconazole trifloxystrobin water dispersible granules.

[0040] The technical indicators of water-dispersible granules are as follows: suspension rate ≥ 90%; wetting time ≤ 30s; moisture ≤ 2.5%; pH value 6.0-9.0; dispersibility ≥ 90%; Persistent foaming (after 1 min) ≤ 20ml; particle size range (0.8mm ~ 1.5mm) ≥ 97%; suspension rate ≥ 85% after heat storage at 54±2°C for ...

Embodiment 3

[0042] This embodiment provides a kind of 42% metconazole·trifloxystrobin water-dispersible granule, and its raw material formula is: metconazole 40%, trifloxystrobin 2%, alkylphenol polyoxyethylene phosphate 3%, alkyl sulfonate 5%, alkylphenol polyether 6%, carboxymethyl cellulose 1%, sodium silicate 3%, kaolin 15%, expansive clay 25%.

[0043] The preparation method of water-dispersible granules is the same as that in Example 2. The technical indicators of water-dispersible granules are as follows: suspension rate ≥ 92%; wetting time ≤ 30s; moisture ≤ 2.5%; pH value 6.0-9.0; dispersibility ≥ 90%; Persistent foaming (after 1 min) ≤ 20ml; particle size range (0.8mm ~ 1.5mm) ≥ 98%; suspension rate ≥ 88% after heat storage at 54±2°C for 30 days.

Abstract

The invention relates to a sterilizing composite containing metconazole and trifloxystrobin. The sterilizing composite containing metconazole and trifloxystrobin comprises an active component and an auxiliary component of a pesticide preparation, wherein the active component comprises metconazole and trifloxystrobin according to the weight ratio of 1:0.03-30, and the active component accounts for no more than 85% of the weight content of the sterilizing composite. In the sterilizing composite, the metconazole and the trifloxystrobin with different mechanisms of action are compounded, and have an obvious synergistic effect. The sterilizing composite has the advantages that the control effect of the sterilizing composite is obvious, the resistance is lowered and delayed, and the toxicity (on the mammal) is not enhanced. In addition, the sterilizing composite provided by the invention has the advantages of small dosage, low cost of the composite and low environmental pollution.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a fungicidal composition for preventing and treating fruit and vegetable rust, downy mildew, cereal powdery mildew, leaf rust and the like. Background technique [0002] Metconazole (Metconazole), chemical name: 5-(4-chlorobenzyl)-2,2-dimethyl-1(1H-1,2,4-triazol-1-ylmethyl)cyclopentanol , is a new broad-spectrum systemic fungicide with excellent protective and therapeutic effects. It can be used as stem and leaf treatment and seed treatment. It is an inhibitor of C-14 demethylase in sterol biosynthesis. Although the mechanism of action is the same as that of other triazole fungicides, the activity spectrum is quite different. Both isomers have fungicidal activity, and the activity of the cis form is higher than that of the trans form. Meconazole has a very broad fungicidal spectrum and excellent activity. Compared with traditional fungicides, the dosage is extremely low and the scope o...
