Embodiment 1 0

[0015] Embodiment one 20% tetrazolium and furazolidium hydrazide suspending agent

[0016] The contents of the following substances are all weight percentages: tetrazolium 5%, furan hydrazide 15%, alkylnaphthalene sulfonate 6%, fatty alcohol polyoxyethylene ether 8%, xanthan gum 1%, Ethylene glycol 2%, silicone oil 0.1%, sodium benzoate 0.1%, deionized water to make up to 100%. The above materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sanded in a sand mill to obtain a 20% tetrazolium and furan hydrazide suspension agent.

Embodiment 2 2

[0017] Embodiment two 32% tetrazolium amide·furan hydrazide suspending agent

[0018] The contents of the following substances are all weight percentages: tetrazolium 4%, furan hydrazide 28%, lignosulfonate 7%, fatty alcohol polyoxyethylene ether 7%, carboxymethyl cellulose 1.5% , 2.5% of urea, 0.1% of silicone compounds, 0.1% of potassium sorbate, and deionized water to make up to 100%. The above materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sanded in a sand mill to obtain a 32% tetrazolium and furazolidium hydrazide suspension agent.

Embodiment 7

[0019] Example Indoor virulence test of tritetraconazole and furazolidide compound to Spodoptera frugiperda

[0020] Test method: With reference to "Indoor Bioassay Test Guidelines for Pesticide NY / T1154.14-2008", the leaf dipping method was used. Statistical analysis was performed with DPS statistical analysis software to calculate the LC of each drug 50 , and calculated the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method, the co-toxicity coefficient (CTC) ≥ 120 showed a synergistic effect; the co-toxic coefficient (CTC) ≤ 80 showed an antagonistic effect; 80 < co-toxicity coefficient ( CTC)<120 showed an additive effect.

Abstract

The invention discloses an application of a fufenozide-containing composition in prevention and control of spodoptera frugiperda, the effective active components of the composition comprise tetratolfenpyrad and fufenozide, and the weight ratio of the tetratolfenpyrad to the fufenozide is 10: 1-1: 20. The composition provided by the invention has an obvious synergistic effect on the spodoptera frugiperda, has an excellent control effect in field application, is obviously better than that of single use of each single agent, is safe to crops, and is an ideal medicament for controlling the spodoptera frugiperda.

Description

technical field [0001] The invention relates to a composition, which is mainly used for controlling Spodoptera frugiperda. The effective active components of the composition are composed of tetrazolium and furan hydrazide, and belong to the technical field of pesticide application. Background technique [0002] Spodoptera frugiperda belongs to Lepidoptera, Noctuidae, commonly known as Fall Armyworm, Fall Armyworm, and Pseudo Armyworm. Its larvae can eat a large number of crops such as corn and rice. Native to the tropical regions of the Americas, it has a strong migratory ability. The larvae feed on the leaves, which can cause defoliation, and then the damage is transferred to other parts. Ridges, which in severe cases can reduce crop yields by more than 80%, have invaded most of the provinces in my country. At present, chemical pesticides are still the main control methods. However, the long-term single and repeated use of chemical pesticides will lead to different degrees ...
