DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a composition containing phospholipids as an active ingredient, a composition for reducing the phytotoxicity of iminoctadine acetate and a mixture thereof, and the above-mentioned active ingredient. The present invention relates to an iminoctadine acetate which does not cause a decrease and a mixed preparation thereof.

[0002]

2. Description of the Related Art In the cultivation of agricultural and horticultural crops, a number of pests are generated, which causes a decrease in quality of products and a decrease in yield. A wide variety of drugs have been developed and effectively used in Japan and overseas as a control measure against pests that cause such quality deterioration and yield reduction. For example, iminoctadine acetate has a broad antibacterial spectrum and is widely used as a fungicide for paddy rice, vegetables, and fruit trees. Also, a number of admixtures have been developed because of their broad antimicrobial spectrum. However, depending on the concentration at the time of use, the iminoctadine acetate may cause phytotoxicity to vegetables such as paddy rice, cucumber, lettuce and fruit trees such as peach, pear, apple and the like. Furthermore, there is no safener for iminoctadine acetate, and its use is limited to low concentrations. Also, JP-A-60-178801 and JP-A-61-2712.
According to the publication No. 02, total carbon 9 in iminoctadine acetate
Carboxylic acid having the above lipophilic group, sulfuric acid monoester,
A composition has been reported in which a sulfonic acid salt and a phosphorus oxyacid are added to reduce the phytotoxicity and have no reduction in efficacy. However, although the composition has an excellent effect of alleviating phytotoxicity, its effect on various diseases is inferior to that of iminoctadine acetate, and it is necessary to increase the concentration at the time of use. Further, pesticide compositions using phospholipids are disclosed in JP-B-51-18501 and JP-B-56-185.
Japanese Patent Application Laid-Open No. 140910/1990 and Japanese Patent Application Publication No. 2-193909 are known. They are used as fungicides for agricultural and horticultural fungicides, acaricides, and machine oils, respectively, but none have been used as safeners for iminoctadine acetate.

[0003]

In view of the above, there is a demand for a safener for iminoctadine acetate which has an excellent safer effect and does not reduce its efficacy. The present inventors have made intensive efforts to solve these problems, and as a result, by incorporating iminoctadine acetate salt with a phospholipid as an active ingredient, a phytotoxicity-reducing agent having excellent phytotoxicity-reducing effect and no reduction in efficacy, and We have developed an iminoctadine acetate salt containing a component and having reduced phytotoxicity, and a mixture thereof. As apparent from the above description, an object of the present invention is to provide an iminoctadine acetate salt and a mixture thereof with reduced phytotoxicity.

[0004]

Means for Solving the Problems The present invention provides the following (1):
It has the configuration of (2). (1) A composition for reducing the phytotoxicity of iminoctadine acetate and a mixture thereof containing a phospholipid as an active ingredient (2) 1 to 40 parts by weight of phospholipid, iminoctadine acetate or 99 to 60 parts by weight of iminoctadine acetate mixture A germicidal composition for agricultural chemicals, the phytotoxicity of which has been reduced.

The configuration and effect of the present invention will be described in detail below. More specific aspects of the present invention are as described in A or B below. A. It is a composition for reducing harmful effects characterized by containing 5 to 40 parts (by weight) of a phospholipid, and is used by adding a predetermined concentration to a diluent of an existing iminoctadine acetate and a mixture thereof. B. In the pesticidal composition in which the phospholipid is added to the iminoctadine acetate and its mixture, the compounding ratio is suitably 1 to 40 parts by weight, preferably 3 to 10 parts by weight. The phytotoxicity-reducing compositions and pesticidal compositions shown in A and B can be used by diluting with water at the time of spraying and adding various surfactants to make them into wettable powders, powders, emulsions, or flowables. desirable.

[0006] The phospholipid as an active ingredient of the present invention is a generic term for lipids containing phosphorus and nitrogen, and is produced from oil seeds such as soybeans, egg yolks, etc., and more specifically, soybean phospholipids. Rapeseed phospholipid, cauliflower phospholipid, cottonseed phospholipid, egg yolk phospholipid and the like can be used.
