example 1

[0017] Bioassay Example 1: Toxicity determination of indoxacarb and tebufenozide complex against Spodoptera exigua

[0018] Test object: resistant beet armyworm larvae (resistance to beta-cyhalothrin is more than 500 times as measured by drug resistance)

[0019] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". The third instar larvae with uniform growth were selected, placed in a petri dish with a diameter of 9 cm containing 10 grams of fresh artificial feed, 10 heads per dish, 5 dishes per treatment, and sprayed with a PottER spray tower at a pressure of 50 PSI. Spray one dish at a time, each dish is sprayed with 1 ml of liquid medicine, and the blank control is sprayed with the same amount of water. Typically 6 concentration gradients are set up per treatment. The treated petri dishes were placed in a 25°C, 12H / 12H light incubator for cultivation, and the number of dead and living insects was checked for 72 hours, and the ...

Embodiment 1

[0031] Example 1: 22% indoxacarb·methoxyfenozide wettable powder

[0032] Indoxacarb 20%

[0033] Methihydrazide 2%

[0034] Sodium Lauryl Sulfate 2%

[0035] Sodium lignosulfonate 5%

[0036] White carbon black 10%

[0037] Kaolin topped up to 100%

[0038] The active ingredients, various auxiliaries and fillers are fully mixed according to the proportion of the formula, and after being pulverized by an ultra-fine pulverizer, 22% indoxacarb·methoxyfenozide wettable powder is obtained.

[0039] Methifenozide in this embodiment can be replaced by tebufenozide, chlorfenozide, tetrafenozide and pyrazine to form a new embodiment.

[0040] This embodiment is applied to the prevention and treatment of tea inchworm. The 22% indoxacarb·methoxyfenozide wettable powder was diluted and sprayed by 5000 times of water, and the control effects were 84.3%, 95.5% and 91.4% respectively at 1 day, 7 days and 15 days after the treatment. 15% indoxacarb suspending agent is 3500 times and 2...

Embodiment 2

[0041] Example 2: 20% indoxacarb·tebufenozide aqueous emulsion

[0042]Indoxacarb 15%

[0043] Tebufenozide 5%

[0044] N-Methylpyrrolidone 10%

[0045] Calcium Dodecylbenzene Sulfonate 5%

[0046] Agricultural Milk 600# 5%

[0047] Water top up to 100%

[0048] Add the original drug, solvent and emulsifier together to dissolve into a uniform oil phase; mix the water-soluble components with water to prepare the water phase; under high-speed stirring, mix the oil phase with the water phase to prepare 20% indene wormcarb·teozide water emulsion.

[0049] The tebufenozide in this embodiment can be replaced with methoxyfenozide, chlortetrafenozide, tetramelizide and pyrazine to form a new embodiment.

[0050] This embodiment is applied to control cabbage beet armyworm. The 20% indoxacarb·tebufenozide aqueous emulsion was diluted and sprayed by 4000 times of water, and the control effects were 87.1%, 93.7% and 90.9% respectively at 1 day, 7 days and 15 days after the treatmen...

Abstract

The invention relates to a pesticide composition which comprises effective ingredients including indoxacarb and one of the following bishydrazide insect growth regulators: tebufenozide, methoxyfenozide, halofenozide, chromafenozide and 1,2-Dibenzoyl-1-tert-butylhydrazine, wherein the mass ratio of the indoxacarb and the bishydrazide insect growth regulator is from 10:1 to 1:50, preferably from 5:1 to 1:20. After being compounded, the indoxacarb and the bishydrazide insect growth regulator have obvious synergized action and are used for preventing insects of crops, such as fruit trees, cotton, rice, vegetables, and the like, in particular Lepidoptera insects.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing indoxacarb and a dihydrazide insect growth regulator. Background technique [0002] In recent years, due to single drug use and unscientific drug use, many pests have developed resistance to the currently used pesticides, such as diamondback moth, cotton bollworm, etc., which has become a major problem in chemical control. At the same time, the frequent application of pesticides also increases the burden on farmers and aggravates environmental pollution. Therefore, new varieties of pesticides with high efficiency, low toxicity and environmental protection are urgently needed. [0003] Indoxacarb is a new type of oxadiazine insecticide. Its insecticidal mechanism is to block the sodium ion channel in the nerve cell of the pest, so that the nerve cell of the pest loses its function and is paralyzed, and the coordination ability is reduced. , ev...
