Abstract

An insecticidal composition is provided comprising 22-25% by weight of acesulfame and 15-18% by weight of phenfenine. It has been found that this specific weight ratio of acesulfame and bifennin shows a hitherto unknown and surprisingly strong synergistic effect on controlling insects, exceeding the previously reported effect of the pesticidal composition.

Description

Insecticide composition

The present invention generally relates to compositions for controlling insects. In particular, the present invention provides a pesticidal composition comprising a specific amount of thiamethoxam and bifenthrin which exhibit particularly strong synergistic effects in insect control.

Insect attack represents a major threat to important economic crops. The yield of plants such as fiber plants, vegetables, sugar cane, legumes, cereals, pastures is adversely affected by insect attack.

Chemical control is an important way to prevent and control pests in agriculture. However, environmental and economic requirements for modern insecticides (eg, in terms of spectrum of action, toxicity, selectivity, application rate, formation of residues, and good preparation capabilities) are increasing.

Insecticides known as neonicotinoids represent a well-known class of insecticides with broad spectrum insect control. Compared to previously used organophosphorus and urethane insecticides, neonicotinoids are less toxic as insecticides and provide similar broad-spectrum control of large numbers of pests that destroy crops. One representative of the neonicotinoid is 3-[(2-chloro-1,3-thiazol-5-yl)methyl]-5-methyl-N-nitro-1,3,5-acean Diazine-4-imine, known under the generic name Syracuse, is a widely used commercial agrochemical product. Sai Su An and its preparation method are disclosed for the first time in EP 0 580 553. It is a broad-spectrum systemic insecticide, and plants can be quickly absorbed and transported to all parts of the plant (including pollen), where speed is used to prevent insects from feeding. The compound is absorbed in the stomach of an insect or absorbed by direct contact, including through the insect's tracheal system. Sai Suoan acts by interfering with the nicotinic acetylcholine receptors in the central nervous system and eventually paralyzing the muscles of the insects.

Another class of well known insecticides are pyrethroids. This is axonal stimulating toxin ( excitotoxins ) whose toxic effects are mediated by preventing the closure of voltage-gated sodium channels in the axons. A representative of the pyrethroids is 2-methyl-3-(phenylphenyl)methyl(1S,3S)-3-[(Z)-2-chloro-3,3,3 Trifluoroprop-1-enyl]-2,2-dimethylcyclopropane-1-carboxylate, the known generic name is Phenfenin. Like other pyrethroids, bifenin is chiral and has two different enantiomers: 1S-cis-bifenin and 1R-cis-biphennin. Its combination with voltage-gated sodium channels leads to so-called after potentials and leads to a continuous discharge of the final axons, thereby rendering the target insects incapable of mobility.

Because of the problems, for example, the problem of resistance to known active compounds, there is a continuing need to develop new insecticides which, in some respects, are at least advantageous over their known counterparts. Recently, insecticidal compositions containing two or more compounds from different classes of insecticides have been proposed. Compositions comprising acesulfame and bifennin have been reported in the art.

CN 101919401 B discloses a pesticidal composition comprising acesulfame and bifennin in a weight ratio of from 20:1 to 1:5, preferably from 15:1 to 1:1. One embodiment discloses a composition comprising 5% Sai'an, 10% diphenanthrene, 8% anionic emulsifier, 6% nonionic emulsifier, 15% cyclohexane, 5% methanol, and supplemented to 100% Xylene.

CN 102027986 B discloses a pesticidal composition comprising Bifennin and Sai Suan in a quality ratio of 100:1 to 1:10.

US 8,133,499 discloses liquid termiticide compositions comprising pyrethroids (e.g., bifenin) and neonicotinoids (e.g., Saxon). The composition provides continuous chemical masking and increased termite mortality at low application rates. In this composition, bifenin is present in an amount of from 0.0005 to 0.50% by weight of all components, and the amount of acesulfame is present in an amount of from 0.0005 to 0.50% by weight of all components.

US 2008/319023 discloses a pesticidal composition comprising a mixture of a pyrethroid and a second insecticide selected from the group consisting of acesulfame. The composition contains from 0.001% to 0.005% by weight of phenfenine and from 0.0025 to 0.02% by weight of acesulfame.

Although some of the effects of the combination of Sai Su An and Bifennin on insecticidal control have been reported, and the amount of pesticide required to effectively control pests has been reduced, the latest environmental protection and consumer interest need to be relatively The application rate and the lower application rate of such compositions, especially in Agricultural industry.

Accordingly, it is an object of the present invention to provide a more effective insecticidal composition that overcomes the problem of developing resistance and reduces the need to apply a large amount of the composition to plants for effective control of pests, such as certain insects.

It has now surprisingly been found that insecticides comprising about 22-25% by weight of cytosine and about 15-18% by weight of phenfenine are compared to previously reported compositions comprising cyanohydrin and phenfenine. The composition showed a significantly stronger synergistic effect.

Also preferably, the amount of bifenin is from about 15.4% by weight to about 17.6% by weight, more preferably from about 15.8% by weight to about 17.2% by weight, still more preferably from about 16.1% by weight to 17.00% by weight, more preferably about 16.3% by weight. -16.9 wt%, most preferably from about 16.5% by weight to 16.7% by weight. The optimum amount of bifenin in the insecticidal composition is about 16.6% by weight.

A preferred combination is from about 23% to about 24% by weight of acesulfan and from 16% to 17% by weight of phenfenine, and a more preferred composition contains from about 23.3% to about 23.5% by weight of acesulfame and about 16.5 weight. The best composition contains 23.4% by weight of piracetin and 16.6% by weight of phenanthrene.

Saikuan and Bifennin may be present in the composition or applied in any amount relative to each other to provide a synergistic effect of the mixture. Specifically, the weight ratio of the Sai An An and Bifennin in the composition is from about 1.7:1 to about 1.2:1, preferably from about 1.65:1 to about 1.25:1, more preferably from about 1.6:1 to about 1.3. More preferably, the composition is from about 1.55:1 to about 1.35:1, more preferably from about 1.5:1 to about 1.35:1, more preferably from about 1.45:1 to about 1.35:1.
