Description

  The present invention relates to a pest control composition and the like.

  Capsicum annuum L. is a plant widely used all over the world as a raw material for foods, spices, medicines and the like. The main pungent components in the plant are capsaicin ((E) -N-[(4-hydroxy-3-methoxyphenyl) -methyl] -8-methyl-6-nonenamide) and dihydrocapsaicin. Furthermore, although it is a small amount as a pungent component, 12 or more types of compounds, such as nordihydrocapsaicin, homocapsaicin, and homodihydrocapsaicin, are contained. These compounds are compounds in which a fatty acid is bonded to vanillylamine with an acid amide bond, and are usually called capsaicinoids. In addition, compounds such as capsinoids and capsaicinoid glycosides are already known as compounds that are similar in structure to capsaicinoids but have almost lost the pungent taste. Capsinoid is a general term for a group of compounds represented by capsiate. The compound included in the compound group is a compound obtained by esterifying a fatty acid with vanillyl alcohol (see, for example, Non-Patent Document 1).

  It has been known that the various compounds described above have various physiological activities (for example, see Non-Patent Documents 2 and 3). Specifically, for example, as a pest control composition in combination with an insecticide, one compound selected from chlorpyrifos, profenofos, methylparathion, parathion, methyldemeton, cyhalothrin, thiodicarb, mesomil, and amitraz and vanillylamine or vanillyl alcohol A single compound selected from chlorpyrifos, profenophos, methylparathion, parathion, methyldemeton, cyhalothrin, thiodicarb, mesomil, and amitraz can be used by mixing a compound of fatty acid with an acid amide or ester bond or a glycoside thereof. It has been reported that the insecticidal activity is improved as compared with the case (see, for example, Patent Document 1). However, there is a report on the combined use of 4-phenoxyphenyl (RS) -2- (2-pyridyloxy) propyl = ethyl and vanillylamine or vanillyl alcohol in which a fatty acid is an acid amide or ester bond or a glycoside thereof. Not yet known.

When carrying out production activities such as agriculture and livestock, or when storing these products, various pests that harm them may be generated, and production efficiency may be significantly reduced. Until now, various drugs represented by insecticides and acaricides have been widely used in order to prevent these injuries.
However, many of these drugs are chemically synthesized compounds, and it is desired to treat them with as low a dose as possible from the viewpoint of the effect on the environment.
In addition, if the same drug is used frequently, pests of the pest are caused by the drug, resulting in a population that is less sensitive to the drug. As a result, a higher dose is required to control the useful organism using the drug. Processing with is required. New drugs are often effective for controlling such low-sensitivity pests. However, since the cost of developing new drugs is enormous in recent years, low-sensitive pests can be used while using conventional drugs. Therefore, development of a pest control agent having an excellent control effect is strongly desired.

Hereinafter, the present invention will be described in more detail with reference to formulation examples and test examples, but the present invention is not limited to these examples.
First, formulation examples are shown. In addition, a part represents a weight part.

Formulation Example 1
An emulsion is obtained by uniformly mixing 5 parts of Compound A, 5 parts of Compound B1, 8 parts of polyoxyethylene styryl phenyl ether, 2 parts of calcium dodecylbenzenesulfonate and 80 parts of xylene.

Formulation Example 2
4 parts of compound A, 20 parts of compound B1, 3 parts of sodium dodecylbenzenesulfonate, 3 parts of sodium ligninsulfonate and 70 parts of diatomaceous earth are uniformly mixed and pulverized with a jet air mill to obtain a wettable powder.

Formulation Example 3
Compound A (0.5 part), Compound B1 (1 part), talc (48.5 parts) and clay (50 parts) are mixed and stirred uniformly to obtain a powder.

Formulation Example 4
Add 10 parts of Compound A, 5 parts of Compound B1, 5 parts of sodium dodecylbenzenesulfonate, 30 parts of bentonite and 50 parts of clay, and mix well. Next, an appropriate amount of water is added to this mixture, further stirred, granulated with a granulator, and dried by ventilation to obtain granules.

Formulation Example 5
After 5 parts of polyoxyethylene styryl phenyl ether sulfate, 20 parts of 1% xanthan gum aqueous solution, 3 parts of smectite mineral and 57 parts of water are mixed uniformly, and after adding 5 parts of Compound A and 10 parts of Compound B1, the mixture is stirred well. The wettable powder is obtained by wet grinding with a sand mill.

Formulation Example 6
0.02 part of Compound A and 0.1 part of Compound B1 are dissolved in 10 parts of acetone, and 99.88 parts of this solution is solid feed powder for animals (solid feed powder for breeding CE-2: manufactured by CLEA Japan, Inc.). After uniformly mixing, the acetone is air-dried to obtain a poisonous bait.

Next, test examples show that the composition of the present invention is useful as a pest control agent. As for the theoretical value of the insecticidal (eggicide) rate expected when two kinds of active ingredients are mixed and processed, the calculation of Colby usually used for evaluating the synergistic effect of agricultural chemicals such as herbicides It calculated | required by using a type | formula (namely, E = X + Y- (X * Y / 100)).
X: Insecticidal rate when active ingredient A is treated with Mppm (%)
Y: Insecticidal rate when active ingredient B is treated with Nppm (%)
E: Theoretical value of the insecticidal rate expected when active ingredient A is treated with Mppm and active ingredient B with Nppm (%)
When the actual insecticidal (ovicidal) rate is higher than this theoretical value, it is determined that there is a synergistic effect.

Test example 1
Compound B1 emulsion was obtained by dissolving 10 parts of Compound B1 in 90 parts of a solvent (90 parts of xylene + 10 parts of Solpol 3005X). A spreading agent (New Reno: manufactured by Nippon Agricultural Chemicals Co., Ltd.) is added to a solution obtained by mixing a water dilution of a predetermined concentration of Compound B1 emulsion and a water dilution of a predetermined concentration of Compound A emulsion (Ranoh emulsion, manufactured by Sumitomo Chemical). A test drug solution was prepared by adding the spreading agent so that the amount of the spreading agent was 1/5000 in volume.
On the other hand, cabbage was planted in the pot and grown to the 4th leaf stage. The cabbage leaves were cut one by one, cut into a 3 cm diameter circle with a cork borer, and placed in a film case (3 cm diameter) filled with 1% agar. 15 adult adults of tobacco whitefly having low sensitivity to Compound A (tobacco whitefly strains having low sensitivity to Compound A collected from house tomatoes in Fukuoka Prefecture) were placed and spawned on cabbage leaf pieces. After 72 hours, all adult worms were removed to obtain eggs within 72 hours after birth.
Next, the test chemical solution was poured onto the cabbage leaf pieces in the film case, whereby the cabbage leaf pieces and the eggs on the cabbage leaf pieces were subjected to a chemical immersion treatment for 30 seconds. After 8 days of treatment, the number of eggs hatched and the number of eggs not hatched were investigated, and the ovicidal rate was calculated according to the following formula. The results are shown in Table 2.

  Egg kill rate (%) = number of eggs not hatched / (number of eggs not hatched + number of eggs hatched) × 100

  According to the present invention, there is provided a pesticidal agent having an excellent pesticidal effect even at a lower dose while utilizing a conventional drug, and also having an excellent pesticidal effect on a less sensitive pest. Is possible.
