2 and R41j (which can be located interchangeably in the ortho and para positions) and a fungicide which can be used for the chemical control of phytopathogenic fungi and bacteria. These agents are preferably used as agents for controlling fungal and bacterial diseases in the cultivation of grains, fruits, potatoes, vegetables and ornamental plants, as well as as soaking agents for agricultural and horticultural harvests and as agents for protecting stored materials. , potato soft rot (lrvinia #pR)% dry rot (Fu
Mycosis and bacteriosis of P. sariuia plants accounts for an estimated $20 billion or more in crop and stored crop losses each year. Besides several hand tools, the use of plant protection agents against many plant diseases is of decisive significance in producing a high yielding capacity of field plants and preserving the stored crops. However, no sufficiently effective or sufficiently practical solution is yet known (storage-complex rot, peel disease in fruit mounting part II), and this is particularly true for soaking potatoes.
Except for the ring, it falls under #i as a plant protectant against bacterial diseases. One global problem is the loss of crops during storage due to spoilage, especially in the case of parasitic infestation. The possibility of chemical control directed against the pathogens of class 1 and bacterial diseases of Potato spp. is known from the specialized literature. Among the numerous active substances used, dry rot (Fusarium #PP- and Phom

Peridazole (Pt*'berilagol), benoi

Previously, only the antibiotic chloramphenicol could be used for effective protection against aspB (
(see East German Economic Patent No. 42.5), it has been established that for combined outbreaks of all diseases it is advantageous to use a mixture of benzindazole fungicides and chloramphenicol. (see East German Economic Patent No. 1l-Q423 and East German Economic Patent No. 15rJ, 4p2'7). This admixture forms the basis of an advantageous processing method for potatoes and is important for their subsequent storage.

The use of chloramphenicol, the first commonly used antibiotic and the first synthetically produced antibiotic, was considered dangerous as a soaking agent for storage.

The World Health Organization (W'HO) recommends that antibiotics used in medicine not be used for purposes other than medicine. For this reason chloramphenicol is not used internationally for plant protection purposes.

Keep in mind the fact that pre-emergence treatment with chloramphenicol as a plant protection agent for agricultural purposes introduces diseases into the environment and that consideration must be given to reducing bacterial sensitivity. has declined, which is extremely significant (RO8INTIIAL et al. 1977). Sensitivity is often found in resistance factors (R-plasmids), which species, genera and families are transmitted between orders by serial conjugation or transduction in bacteria and are therefore susceptible to treatment. (WHO, 1975: RISOHl, 1975).

General ceremony! The antimicrobial compound expressed by (see East German Economic Patent No. 131.746), which are distinguished by their excellent antimicrobial properties, which are favored for corresponding uses in medicine and veterinary medicine. Furthermore, phenol derivatives such as chlorophenol, pentachlorophenol, cresol, chlorcresol,
Benzylphenol, benzylchlorophenol and thymol are also known to have antimicrobial activity and are therefore considered as possible mixture ingredients for fungicides for increased action and broadening of the range of action. used for. The disadvantage of these compounds/) is the very high toxicity of some to plants and to bleeding animals, which precludes their use in plant protection. Therefore, the object of the present invention is to enable a maximum fungicidal and bactericidal action with a minimum of phytotoxicity to the plants, and which does not have the above-mentioned disadvantages, especially in the treatment of stored potatoes. There is a possibility that it will be effective against diseases of plants that have not been able to produce sufficient KvJ eyelids (for example, compound rot disease of storage soda, pericarp disease in fruit cultivation, etc.). The purpose is to apply an agent to control pathogenic Ma and rot of stored violet potatoes. .

In order to achieve the above objectives, the often dangerous antibiotic chloramphenicol was replaced with a more advantageous compound and, in the case of potatoes, the total loss due to spoilage during storage was avoided. 60-90% reduction, increase potato yield by 5-10%, improve plant quality, and reduce at least the appearance of damping off and black blight (infestation due to 50- can be reduced.

The inventors surprisingly found that the general formula! Antimicrobial compounds represented by various fungicides, lf# mixed with benzimidazole-based chloride #Iσ, have excellent detoxification effects against true virulence and bacterial pathogens infected alone or in combination. It has been found that the compounds exhibit the same effects as described above, and even more so than those described for the individual corresponding compounds.
