By enhancing the fungicidal effects of each chemical and compensating for the shortcomings of G1 and S Recommendations 11, we can expand the bactericidal spectrum and spray small doses against various diseases of various useful crops. The great thing about this is that you can stably exert the extremely high G) intercostal z effect just by doing so. Its special control effect is synergistic and synergistic against cucumber downy mildew, cucumber powdery mildew, cucumber bacterial spot, tomato gray mold and other fruit tree diseases such as apple leaf spot and plum canker. In recent years, the spread of agricultural and horticultural techniques across the country, combined with the increased demand for fresh vegetables, has led to a shift from seasonal outdoor cultivation to the use of greenhouses and crow rooms. Facility horticulture is in progress

[Then, vegetables began to be grown all year round. In greenhouse horticulture, the cultivation slope is very different from the cultivation area.
In Saku, various diseases occur together with the high temperature and humidity. Particularly in recent years, as the cost of energy sources such as oil has skyrocketed, vinyl greenhouses and glass greenhouses lined with vinyl are becoming increasingly popular. In such energy-saving greenhouses, various crop diseases occur at night, and the insect environment conditions are suitable for the growth of heat and humidity, which causes the various diseases to flourish and cause significant damage. As a countermeasure against this, it is true that we have resorted to non-labor-saving chemical control in which various chemicals are sprayed multiple times before and after the outbreak of the disease.
Spraying such large amounts of chemicals poses a major problem from the standpoint of crop contamination, chemical residue in crops, and health management for those spraying mulberry shavings. Therefore, in order to provide safe fresh vegetables for over a year, the facility staff is required to reduce the level of drug use and the number of times the drug is used. The first step in the development of technology to address these issues is the development of a new pest control method that can simultaneously control four types of diseases that occur in greenhouses, etc., in a labor-saving and efficient manner. In view of these circumstances, we conducted extensive studies using a large number of compounds.As a result, we found that istamycin A, istamycin B f7: i, and one of these salts include basic copper chloride, basic copper sulfate, and +N. Combining rylene + one pole selected from cupric chloride and copper (from this, cucumber and disease,
Cucumber powdery mildew, cucumber bacterial spot, tomato gray mold, apple spot! ! It was discovered that various diseases such as leaf blight and canker blight can be effectively controlled in a labor-saving and labor-saving manner. Istamycin A1, istamycin B, or its salts are disclosed in Japanese Patent Application Laid-Open No. 1456-1456.

. (The Journal of Antibiotic Typhoid Fever) No. 82
Vol. 9, No. 964-966 (1979), known antibiotics' (1979), the production method of which is described. It is also known to be useful as a l agent.
1 These antibiotics (stronger antibacterial agents than those such as succulent leaf blight, rice leaf blight, rice bacterial blight, cucumber bacterial spot, citrus canker, eggplant IV blight, and flanaceae soft cormorant) It is an agent that is useful for controlling various diseases caused by fungi, especially as a fungicide for agriculture and horticulture. 4-Various filamentous diseases
There is a problem that the control effect against this species is low, and the control effect lacks sustainability. In order to make the IJ practical (constantly stable and bright effect as a simultaneous control agent for various diseases), it is necessary to spray a large amount of highly concentrated chemicals,
It is necessary to spray the medicine i'+II many times before and after the outbreak of the disease. Spraying such a large amount of chemicals is undesirable from the standpoint of 1C crop contamination and crop residue, as described above, and requires improvement. In addition, basic chloride steel, basic chloride steel, cupric hydroxide, and oxin t, which are the active ingredients of one, "Pesticide Handbook 1981 Edition" (same as above) @ pages 180 to 186,
It is known from pages 186 to 145 of ``Modern Pesticides M. IV J'' (published by Asakura Shoten on December 5, 1972).And these copper agents are extremely harmful to humans and animals.
It has a low and relatively broad spectrum of pesticidal activity. However, the control effect of these copper agents is limited to the preventive spraying effect, and no control effect is observed at all by spraying after the invasion of pathogenic bacteria, that is, by therapeutic spraying. The name of the present invention is to provide a practical, labor-saving control agent that can simultaneously control the disease by spraying at a low dose. I did a thorough examination of the combination of the two. As a result, IllJ and Istamycin A and Istamycin B may cure these deficiencies;
Combining at least 1 of these salts with t4 selected from basic copper chloride, basic copper chloride, cupric hydroxide and copper oquinone (from this, 14+'i) cucumber udon (C, cucumber udon) It shows a remarkable control effect on various types of insect pests such as this disease, Cymori spot and thin head disease, etc. with low feeding rate, and simultaneously and sustainably controls them.
This is a small amount of work. Therefore, 1) the agricultural and horticultural fungicide of the present invention has fewer nuisances than conventional agents, is labor-saving and economical, and has excellent practicality, especially for gardening purposes. It can be used as a pest control agent. These effects of the present invention I can be obtained by using each active ingredient of the present invention alone.
Historically, it was not possible to produce a similar product, and the active ingredients were mixed together and worked synergistically or synergistically. The agricultural and horticultural fungicide of the present invention is designed to protect these beloved pieces of bamboo, and has the following benefits: 11. Even if the amount is reduced from 1/4 to less than 1/10 when using Taniya's agent alone, the control effect is still sufficient! It can be used with peace of mind without worrying about toxicity that may cause damage to people, etc., or chemical damage that may cause damage to crops. In addition, by using the agricultural and horticultural fungicide of the present invention, the following diseases can be expected: Katayu, νuriheto, cucumber powdery mildew, cucumber anthracnose,
4 Bacterial bacterial spot disease of lily, soft rot of Chinese cabbage, white leaf blight of rice,
Rice blight, citrus black spot J14, power/killer blight, eggplant night blight, pear black spot, tomato late blight, tomato ring spot blight, tomato bacterial wilt, tomato leaf σ disease, oilseed rape blight It is a wide range of diseases including diseases. Examples of the chair 274,974 that can be used in the present invention include hydrochloride, nitrate, phosphate, and carbonate, but are not limited to these. do not have. When carrying out the present invention, the active ingredient compound is diluted with a phase in the commonly used forms, such as wettable powders, emulsions, powders, DI, (driftless) type powders, and powders for flow dust. They may be formulated into formulations such as sol formulations, granules, fine granules, and supplements, and then used according to known methods. The carriers used in the present invention include old ones, such as solid carriers such as clay, talc, bentonite, kaolin, diatomaceous earth, and silica, and benzene, xylene, toluene, kerosene, and alcohols (
