Embodiment 1

[0018] Example 1: Compound toxicity test of methoxyfenozide and dimehypo, monosultap or cartap

[0019] 1. Toxicity test of methoxyfenozide and insecticide

[0020] Synergistic test of methoxyfenozide and dimehypo compound, using rice leaf roller (Chaphalocrocismedina) as the test object. The specific method is:

[0021] Sensitive test insects were collected from the rice leaf rollers larvae raised with rice seedlings in the greenhouse of Shenzhen Nopoxin Company Research Institute, and resistant test insects were collected from Lingshui County, Hainan Province. The test drug methoxyfenozide was from Dow AgroSciences, USA, and the stock solution of dimehypo was from Hubei Xianlong Chemical Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". The test adopts a petri dish with a diameter of 9 cm in which young rice l...

Embodiment 2

[0051] Example 2: Preparation of methoxyfenozide and dimehypo compound preparation and field test of medicament

[0052] 97.6% methoxyfenozide 10.25g

[0053] 25% dimehypo mother solution 40g

[0054] Octylphenol ethoxylate 5.0g

[0055] Phenol formaldehyde resin polyoxyethylene ether 3.5g

[0056] Xanthan gum 0.5g

[0057] Deionized water up to 100g

[0058] Add the above components in the mixer successively according to the amount of the formula, stir evenly after shearing, and make 100 grams of 20% methoxyfenozide dimehypo water emulsion (the mass ratio of methoxyfenozide and dimehypo is 1:1).

[0059] Dilute and spray 20% methoxyfenozide dimehypo emulsion with 24 g / ha of active ingredient in water to prevent and control rice leaf roller. The control effect was 94.3% 3 days after application, and the 30% methoxyfenozide water emulsion and 18% dimecid dihydrate emulsion were used according to the same method and dosage, and the control effects were 80.7% and 43.2% resp...

Embodiment 3

[0061] Example 3: Compound preparation of methoxyfenozide and monosultap and field test of medicament

[0062] 97.6% methoxyfenozide 20.67g

[0063] 95% monosultap technical 1.1g

[0064] Alkylarylpolyoxypropylene polyoxyethylene ether 7g

[0065] Sodium polynaphthalene sulfonate 4 g

[0066] Xanthan gum 1 g

[0067] water up to 100g

[0068] The above components are mixed evenly according to the amount of the formula, and 100 grams of 21% methoxyfenozide monosultap suspension is obtained after high-speed shearing (the mass ratio of methoxyfenozide and monosultap is 20:1) .

[0069] Dilute and spray 21% methoxyfenozide monosultap with 20 g / ha of active ingredient in water to prevent and control rice stem borer. The control effect was 96.2% 3 days after application, 24% methoxyfenozide suspension concentrate and 25% monosultap suspension were used in the same method and dosage, and the control effects were 82.2% and 21.6% respectively 3 days after application. Significan...

Abstract

The invention discloses a farm chemical composition and use of the farm chemical composition in agriculture. The active ingredients of the composition comprise methoxyfenozide and nereistoxin pesticides, wherein the mass ratio of the methoxyfenozide to the nereistoxin pesticides is 20:1 to 1:80. The composition has the advantages of having a synergistic effect which is more obvious on resistant pests, reducing medicament consumption and delaying resistance development. The composition can be used for preventing and controlling Lepidoptera with obvious resistance and is particularly suitable for preventing and controlling rice leaf rollers, chilo suppressalis and tryporyza incertulas which have resistance to the nereistoxin pesticides.

Description

technical field [0001] The invention relates to a pesticide composition and application thereof, in particular to a pesticide composition containing methoxyfenozide, which is used to prevent and control resistant pests on plants. Background technique [0002] In the actual process of agricultural production, chemical control is an important means of preventing and controlling pests in agricultural production. In chemical control, the most likely problem is the emergence and development of resistance of bacteria and pests. In agriculture, resistant pests are prone to have short reproductive cycles, large reproductive numbers, and significant generational overlap. [0003] Paddy rice leaf roller (scientific name: Cnaphalocrocis medialis Guenee) is one of the three major pests of rice, and suffers the greatest damage at the pregnancy and heading stages, which can cause 5-30% losses. Due to its characteristics of migration and large reproduction, rice leaf rollers have obvious...
