Description

(54) FUYGYCH; A TALNED COMPOSITION 2.1 hyosubstituted 2,6-dinitroanil Hia is obtained by the interaction of the corresponding Z-xLor-2, 6-dinTr6a yi1No of the general formula P with sodium sulfide and cyan chloride or another tio-substituted agent. 3.3-Azid-2 b-dynyl ioanilines of general formula 1 are obtained from the B-3-chloro-2,6-dinitroanilines of formula II according to the reaction of chlorine-img (its compound with the metal iyid in an inert solution — feftb, fungicidal forms of application; , powders, solutions. Their Polufiot methods common in the manufacture of preparative forms of pesticides; -, - The amount of the compound form "1ula 1 for the fight t grape fluffy Milybyu can vary widely, Aoroishu results get yriy I (5% of the liquid compositions, containing from 2.0 to 10 ppm of active substance.In case of using dust-like compositions, good results are achieved with a content of from OJ, O5 to 5% by weight,% and 6ojfeeJ of the active substance. To combat the pushing of the junction, the compounds are used 10 g to 2 kg per hectare per day are applied to the foliage of the plant, which is the source of a fungal phytophagous phytopes testify to their twist protective effect.

On the day of testing, young leaves are separated. From the grapevine. Each leaf is placed upside down on a leaf. Chsshu Petri (10С) х2пМм) and the base of the stem of the leaf are wrapped

7 (32990 cotton swab moistened with water. In the Petri dish there is a Vatman filter paper placed on top of a stretched plastic base. This base and filter paper hold a sheet over the yoda located on the bottom of the Petri dish. Each test chemical compound is applied by spraying onto the bottom side of the lit and dried; All leafs of Kf are contaminated by spraying sustenance of koidyi on the bottom surface of the sheet and then covered with a whip of Petri dishes. Petri dishes are placed on a shelf in a foggy crmyat at a temperature of 18-2 0 s, light / dark mode - 8/16 h. Illumination (using cool white fluorescent lamps with a capacity of 9140-1 1760 lm / m) After seven days of exposure, examine the leaves with a c-purpose. Observe their symptoms by evaluating the results of -, on the following scale, score: Strong 1 Moderate 2 Weak3 Very weak 4 rfeT lesions 5 ConiDia, used as a graft material, is obtained from newly infected leaf tissue stored at. I wash the conidium from the leaf surface with a brush and bubpend the fe to deionized water. Apply the suspension to the Leaves surface with a spray. The results are shown in table 1. A dash in the table indicates that the compound was not tested, an asterisk means that. the compound is phytotoxic. If the compound is tested in the same concentration several times, then graft the same data. Pros (+) And minuses (-) in the table characterize a weak degree of deviation from the assessment on the scale indicated above, based on a subjective determination. These values can be represented in the following form: 50% or more lesions 121-50% 11-20% - -3 1-10% 0% 5 For comparison, the following compounds are used; , Trading preparation N, N-ethylenebis: (diTiocarbomate) of manganese (maneb) 4,4 -Eistrifluoromethyl-2,6-dinitro.
