Herbicide composition for insecticide and growth promoting

Detailed description of the invention

[Purpose of invention]

[Technical field to which the invention belongs and the prior art in that field]

The present invention relates to insecticides effective for promoting insect growth and cultivation of crops, horticultural crops, arbors and the like, and agricultural chemicals-like for promoting growth.

Wood liquor is an acidic liquid obtained by cooling gas generated during the drying of wood, such as charcoal production. In the past, it was used as a raw material of acetic acid or acetone, or as a preservative, fumigant, human or It was used for uses such as deodorant of livestock fraction.

In recent years, because of the tendency to avoid organic farming, low pesticide farming, and chemically synthesized pesticides, woody sap with high stability to living organisms has been particularly noticed in recent years, and fertilizer production and weeding are added to soil disinfection, stable manure and compost. Increasing use in agriculture, such as control, plant growth, pest control, etc. (see Japan, Special Publication No. 63-24964, Forest Land, p. 28, 1978, Timber Journal 35, pages 564 and 1021).

For the sake solution, the use to organic farming vegetables, home gardening, a tree for the garden or the grass greatly increases because of the safety. Wood grass liquor is usually diluted to about 50 to 1,000 times with water for these agricultural uses, but the effect is slow, and in particular, there is a drawback that a sufficient effect is not obtained in terms of pest control. In order to improve such a point, a method such as mixing a synthetic pesticide with wood vinegar, or the like, has also been necessary to spray insecticide separately.

MEANS TO SOLVE THE PROBLEM As a result of various studies in order to improve the performance of the said wood vinegar, the present inventors were able to remarkably enhance the said pesticidal effect which wood vinegar has by mixing lysolecithin (lysocithin) with wood vinegar.

That is, the first insecticidal and growth promoting wood vinegar composition of the present invention is composed of lysocithin, and the second insecticidal and growth promoting wood vinegar composition of the present invention includes wood vinegar, lysocithin and fatty acids. . Here, the meaning of pesticide and growth promoting wood vinegar composition means that the present invention has almost the same degree as the effect of various pesticides, and has effects such as disease prevention, insect repellent, insecticide, growth promotion, and the like. Say that.

In the insecticidal and growth promoting wood vinegar composition according to the present invention, the weight ratio of wood vinegar / lysorecithin is 20: 80 ~ 97: 3, or the weight ratio of wood vinegar / lecithin lipid is 20: 80 ~ 97: 3, 100 with respect to lysosithin Particular preference is given to containing up to% by weight of fatty acids.

The present invention also relates to a wood-based composition for insecticidal and growth promoting, wherein the lysorecithin used is soy lysorecithin and the fatty acid is an unsaturated fatty acid and / or a heavy chain fatty acid having 8 to 14 carbon atoms.

The wood vinegar in the present invention is generally one obtained at the time of producing charcoal, such as black charcoal or white charcoal, and one obtained by distilling sawdust, waste wood, bark, chaff and the like. Crude wood vinegar is a liquid obtained by cooling a gas generated by charcoal burning or dry distillation such as wood for a long time, and separating the settling tar powder. Crude vinegar can be used as it is, but it is more suitable to remove insoluble matters by filtration or centrifugation. Moreover, distilled crude wood vinegar may be used under normal pressure or reduced pressure.

The components of wood vinegar vary somewhat to some extent depending on the raw material, the manufacturing method, and especially the temperature conditions, but are usually organic acids having a specific gravity of 1.01 to 1.04, water 80 to 90%, pH 2 to 4, and mainly acetic acid as an organic substance, It contains alcohols such as methanol, neutral organics such as acetone, and wastes. It contains almost innumerable ingredients. Year, see page 297). In the present invention, any of these wood vinegar solutions can be used. Moreover, what neutralized by adding alkaline components, such as caustic soda, to ordinary wood vinegar can also be used.

On the other hand, what mechanisms are the effects of soil disinfection, growth of microorganisms, growth of microbes, control of weeds, growth of plants, increase of plant resistance, pest control, etc.? It is in an unknown state even in the present.

The lysolecithin used in the present invention is a monoacyl lecithin deacylated with phospholipase A derived from lecithin and egg yolk lecithin derived from plant seeds such as soybean or rapeseed, usually in the pancreas. Those treated with the derived phospholipase A-2 are used. In particular, soy lysorecithin made from soybean lecithin, which is a by-product of refining soybean oil, is cheap and is suitable as a raw material of the present invention. These lysocithins include monoacylglycero lecithins such as risphophosphatidylcholine, risphophosphatidyl ethanolamine, lysophosphatidyl inositol, and lysophosphatidic acid. It is also suitable to increase the content of lysophosphatidylcholine from these mixtures by hydrous alcohol treatment or the like. Chemically synthesized lysolecithin can likewise be used.

It is difficult to make all the lecithin into lysorecithin by the said enzyme treatment, and diacyl body lecithin remains, but the quantity of lysorecithin is 50 weight% or more of the whole lecithin is suitable for the raw material of this invention. If such is the case, the lysolecithin is treated with, for example, a paste-like soybean lecithin containing a common oil component with phospholipase A-2, and then centrifuged to remove the oil and fatty acid by centrifuging the hydrous paste of the lysocithin. good. In addition, after phospholipase A-2 treatment, the fatty acid may be neutralized to some extent and commercialized with oil or the like. After the phospholipase A-2 treatment, a fatty acid may be removed by purifying with a solvent such as acetone. In any case, the amount of lysocithin added to wood vinegar is calculated by the absolute amount thereof.

Unsaturated fatty acids used in the present invention may be fatty acids such as linoleic acid, linolenic acid, oric acid, arachidonic acid, eicosaptanoic acid, docosahexanoic acid, and mixtures thereof, and saturated fatty acids such as palmitic acid and stearic acid may be present. good. Vegetable oil fatty acids such as soybean oil are also suitable in this respect.

The medium chain fatty acid used in the present invention is capric acid, caprylic acid, lauric acid, myristic acid, or a mixture thereof, and a small amount of other fatty acids may be mixed. Therefore, fatty acids such as palm oil and palm kernel oil are also suitable.

In the first aspect of the present invention, lysolecithin is added to the wood vinegar in its weight ratio in the range of 20:80 to 97: 3. The mixing is preferably performed under heating, but in order to avoid loss of volatile components in the wood vinegar solution, it is preferable to perform the mixing at 80 ° C or lower. The mixing period may be mixed beforehand and diluted upon use, or may be diluted after mixing both immediately before use. Then, the diluted wood vinegar and the aqueous solution of lysolecithin may be mixed. The amount of wood vinegar in the composition may be 20% by weight or less, or the amount of lysorecithin may be 3% by weight or less. However, even if the weight ratio of lysorecithin is higher than the above range, the dilution rate may be changed depending on the purpose.

In the second aspect of the present invention, wood vinegar and lysolecithin are mixed in a weight ratio of 20:80 to 97: 3, and the fatty acid is added to 100 parts or less in a weight ratio to 100 parts of lysolecithin. Mixing may be any method as long as a homogeneous solution is obtained as in the first case, but in this case, an aqueous solution of lysorecithin is prepared under heating, a fatty acid is dissolved in it, and then mixed with wood vinegar to easily obtain a composition. .

Three mixing times and dilution methods can be selected arbitrarily.

If the amount of wood vinegar in the composition is 20% by weight or less, or the amount of lysorecithin is 3% by weight or less, the effect of the composition is insufficient. If the amount of fatty acid exceeds the amount of lysolecithin, the fatty acid is not dissolved and precipitates. Not. In the composition of wood vinegar / lysolecithin / fatty acid, the effect equivalent to the former is many in many cases even if the amount of lysocithin is small compared with the composition of wood vinegar / lysolecithin. In addition, although the ratio of wood vinegar / (lysorcithin + fatty acid) should just be 1 or more normally, even if the weight ratio of a lysorecithin and a fatty acid total is more than the said range, a dilution rate can be changed according to the objective.

Wood grass liquor itself is not a pesticide, so rapid action does not occur. However, when used together with conventional pesticides, chemical fertilizers, etc., since the function to enhance their action is large, the action as an agent for reducing pesticides is also expanded. Therefore, it was difficult to realize all pesticide-free farming methods only with wood vinegar, and in particular, the pest control action was insufficient. Nevertheless, the composition according to the present invention surprisingly has a remarkable pest control action, and also has an insecticidal effect.

The penetrating action of lysolecithin is not as strong as for industrial surfactants. It is known to have strong penetration, wetting, and electrodeposition effects in some types of lysoresin / fatty acid mixtures (JP-A 2-203928). However, the effect of the composition of the present invention is that the industrial surfactant, polyoxy ethylene nonyl phenol ether having the same penetration, wetting, and electrodeposition effect as the lysolecithin / fatty acid mixture, the lysorcithin or lysolecithin / fatty acid mixture. If used instead, it cannot be obtained even when added to wood vinegar.

[Technical problem to be achieved]
