Description
INSECTICIDE COMPOUNDS FOR AGRICULTURAL AND HORTICULTURAL USE BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is directed to mixtures of propargite and synthetic pyrethroids, which exhibit synergistic activity as pesticides.
Thrips palmi is a transplanted insect from
Southeast Asia which has caused serious damage to cucumber, watermelon, melon, eggplant and green pepper in recent years. It has no strong natural enemy, and believed to cause more serious growth damage or fruit damage than any other known insect. Compounds such as sulbrophos, oxamil, carbosulphane, cypermethrin, pemfracalp, BMPC, DMTP, cyfulbenzron, etc. have been used in the past. However, none of them has had a sufficient protective effect.
SUMMARY OF THE INVENTION
The compositions of the present invention contain an active ingredient comprising a mixture of A) propargite, and B) a synthetic pyrethroid. The presen invention also comprises a method for controlling undesirable insects which comprises applying an effective amount of a composition according to the present invention to a locus to be protected.
DETAILED DESCRIPTION OF THE INVENTION
The propargite portion of the active ingredient is a well known insecticide sold under the trademark OMITE (Uniroyal Chemical Company) and has the chemical name 2-(4-tert-butylphenoxy) cyclohexyl prop-2-ynyl sulfite. Examples of the synthetic pyrethroid active ingredient are cyfluthrin, fenpropathrin, cyhalothrin, fulvalinate, tralomethrin, etofenprox, fulcytirinate, cypermethrin, permethrin, and fenvalelate.
In the insecticide compositions of the present invention, the propargite component may be present in the amount of from 3 to 1,000 ppm, or more preferably 100-400 ppm. The synthetic pyrethroide type component may be present in the amount of from 1 to 1,000 ppm, or more preferably 10-200 ppm.
Propargite, which is one of the effective
components of the insecticide offered by the present invention, shows almost no effect against
minami-kiiro-azamiuma (also known as Thrips palmi) by itself. In addition, synthetic pyrethroide type
insecticides, which is also one of the effective
components of the insecticide compounds offered by the present invention, does not show sufficient effect against minami-kiiro-azamiuma by itself even in the case of cypermethrin which has obtained the Agricultural
Chemical Registration in Japan. The compositions
offered by the present invention give superior
effectiveness which cannot be obtained by each component
alone .
As it is described in the application example, common forms of agricultural agents such as aqueous solutions, emulsions, dry-flowable, flowable, or smoke agent which contain the propargite and the synthetic pyrethroide type insecticides may be prepared.
Alternatevely, agents which contain the individual active ingredients are prepared and then mixed together later.
The present invention is explained in detail by reference to the following examples.
Example 1
Propargite 30 parts
Tralomethrin 1 part
White Carbon (Silica) 2 parts
Diatmaceous Earth 58 parts
Alkylbenzene sodium sulfonate 2 parts
Lignin sodium sulfonate 7 parts
The above components were uniformly mixed, and dissolved in water to obtain a 31% aqueous solution.
Example 2
Propargite 30 parts
Tralomethrin 1 part
Xylene 44 parts
Dimethylformamide 15 parts
Alkylbenzene calcium sulfonate 4 parts
Polyoxyethylene-alkylphenylether 6 parts
The above components were mixed and melted to obtain a 31% emulsion.
Example 3
A mixed aqueous solution of propargite (BPPS) and synthetic pyrethroid type insecticides was diluted to the concentrations shown in Table 1, and sprayed on individually potted 20-30 cm tall greenhouse grown eggplants (kind: Kokuyo) which were severely infested by minami-kiiro-azamiuma by using a portable sprayer until the liquid started to drip from the leaves. The number of adult and larvae of minami-kiiro-azamiuma were counted before the spraying and a few days after the spraying, and its effectiveness compared with the effectiveness obtained by spraying them individually. The results are shown in Table 1.
Example 4
The effect of propargite (BPPS) and synthetic pyrethroid mixtures on minami-kiiro-azaiuma was studied in a manner similar to Example 3, except that the emulsion form of Example 2 was used. The results are shown in Table 2.
