Embodiment 1

[0020] Example 1 Determination of indoor biological toxicity of fluazinam, pyridaben and their combination to citrus spider mite

[0021] Test method: Refer to "Indoor Bioassay Test Guidelines for Pesticides NY / T1154.7-2006" and use spot method.

[0022] Statistical analysis was performed with DPS statistical analysis software, and the EC of each drug was calculated. 50 , and calculate the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method, the co-toxicity coefficient (CTC) ≥ 120 shows the synergistic effect; the co-toxicity coefficient (CTC) ≤ 80 shows the antagonism; CTC)<120 showed an additive effect.

[0023] It can be seen from Table 1 that fluazinam and pyridaben have relatively high activity against citrus red spider mites, and the co-toxicity coefficient (CTC) of fluazinam and pyridaben in a combination ratio of 60:1 to 1:60 is greater than 120, showing Synergistic effect, especially the highest synergistic coefficient at a ratio of 1...

Embodiment 2

[0027] Example 2 Determination of indoor biological toxicity of fluazinam, pyridaben and their combination against Tetranychus urticae.

[0028] Test method: Refer to "Indoor Bioassay Test Guidelines for Pesticides NY / T1154.7-2006" and use spot method.

[0029] Statistical analysis was performed with DPS statistical analysis software, and the EC of each drug was calculated. 50 , and calculate the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method, the co-toxicity coefficient (CTC) ≥ 120 shows the synergistic effect; the co-toxicity coefficient (CTC) ≤ 80 shows the antagonism; CTC)<120 showed an additive effect.

[0030] It can be seen from Table 2 that fluazinam and pyridaben have relatively high activity against apple two-spotted spider mite, and the combination ratio of fluazinam and pyridaben is 60:1~1:60, and the co-toxicity coefficient (CTC) is greater than 120. , showing a synergistic effect, especially the highest synergistic coefficie...

Embodiment 3

[0034] Example 3 Determination of indoor biological toxicity of fluazinam, pyridaben and their combination against Botrytis cinerea.

[0035] Test method: refer to "Pesticide Indoor Bioassay Test Guidelines NY / T1156.6-2006", using the plate method.

[0036] Statistical analysis was performed with DPS statistical analysis software, and the EC of each drug was calculated. 50 , and calculate the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method, the co-toxicity coefficient (CTC) ≥ 120 shows the synergistic effect; the co-toxicity coefficient (CTC) ≤ 80 shows the antagonism; CTC)<120 showed an additive effect.

[0037] It can be seen from Table 3 that fluazinam and pyridaben have relatively high activity against Botrytis cinerea, and the co-toxicity coefficient (CTC) of the combination ratio of fluazinam and pyridaben from 60:1 to 1:60 is greater than 120, showing that Synergistic effect, especially the highest synergistic coefficient at a ratio...

Abstract

The invention discloses a composition containing fluazinam and pyridaben. The active ingredients of the composition are composed of fluazinam and pyridaben. The composition further comprises auxiliary components. A weight ratio of the fluazinam to the pyridaben is 60:1 to 1:60. The combination of the fluazinam and pyridaben has obvious synergistic effects on mites and diseases harming crops in a certain range, and a single usage effect is obviously improved. The composition disclosed by the invention is used for controlling harmful mites and pathogenic bacteria of the crops, such as red spiders, two-spotted spider mites as well as gray mold and late blight.

Description

technical field [0001] The invention relates to a pesticide composition and its application technology, in particular to a combination of fluazinam and pyridaben as active ingredients for the prevention and control of agricultural pests. Background technique [0002] Fluazinam, chemical name: 3-chloro-N-(3-chloro-5-trifluoromethyl-2-pyridyl)-α,α,α-trifluoro-2,6-dinitro -ρ-toluidine, 2,6-dinitroaniline compound, is a protective fungicide, which can prevent and treat diseases caused by Botrytis cinerea, against Alternaria, Botrytis, Phytophthora, Agaricus sp., Sclerotinia sp. and Nigella sp. are very effective. At the same time, the study found that fluazinam has a certain systemic property, and the effect of killing acarids is also good. Documents CN105010370A and CN104222125A on the acaricidal effect of fluazinam have been published. [0003] Pyridaben chemical name: 2-tert-butyl-5-(4-tert-butylbenzylthio-4-chloro-3(H)-pyridazin-3-one, belongs to pyridazinone compounds, ...
