Embodiment 1

[0023] Embodiment 1: Benomyl is measured to indoor biological toxicity of spider mite

[0024] As can be seen from Table 1, benomyl has no effect on spider mite LC 50 It is 0.57mg / L, and its activity is higher than that of commonly used drugs abamectin 0.81mg / L and pyridaben 1.23mg / L, indicating that benomyl has higher activity on spider mite.

[0026]

Embodiment 2

[0027] Embodiment 2: Indoor biological toxicity determination of benomyl to Tetranychus cinnabarinus

[0028] It can be seen from Table 2 that benomyl has no effect on red spider mite LC 50 It is 0.40mg / L, and its activity is higher than that of commonly used medicines avermectin 0.58mg / L and pyridaben 0.81mg / L, indicating that benomyl has higher activity against Tetranychus cinnabarinus.

[0030]

Embodiment 3

[0031] Example 3: Determination of the indoor biological toxicity of the combination of benomyl and spirodiclofen against spider mite

[0032] It can be seen from Table 3 that the co-toxicity coefficient (CTC value) of the combination of benomyl and spirodiclofen in the ratio of 80:1 to 1:80 (weight ratio) to spider mite is greater than 120, showing a synergistic effect. In particular, the ratio of 1:1 has the highest synergistic coefficient, and the co-toxicity coefficient (CTC value) reaches 229.2.

Abstract

The invention discloses a benomyl-containing pesticide composition and applications thereof. According to the present invention, the combination of benomyl and spirodiclofen (or spiromesifen) is usedto prevent and control crop pest mites so as to provide remarkable synergistic effect; and compared to the single agent, the composition of the present invention has advantages of significantly synergistic prevention and control effect, effectively reduced pesticide consumption, reduced pesticide use cost and agent service life prolonging, and can reduce the adverse effect on the ecological environment by the pesticide.

Description

technical field [0001] The invention relates to the new application and combined application technology of compound pesticides, in particular to the combination of benomyl and spirodiclofen (or spiromethen) to prevent and control crop spider mite and cinnabar spider mite. Background technique [0002] Benomyl, a systemic fungicide, is metabolized into carbendazim and another volatile butyl isocyanate in plants. It has protective, eradicating and therapeutic effects, and is generally used to prevent and control Ascomycetes, Crop diseases caused by fungi of Deuteromycetes and some Basidiomycetes. [0003] Spirodiclofen, a tetronic acid acaricide, has contact action and no systemic property. It mainly inhibits the fat synthesis of mites, blocks the energy metabolism of mites, has a good killing effect on the eggs, young mites, and nymphs of harmful mites, and has no effect on adult mites, but has the effect of inhibiting the hatching rate of female mites. [0004] Spiromesife...
