Abstract

The use of the compound of the formula <IMAGE> for increasing silk production by silkworms is described. For this purpose, a biologically effective amount of the compound (I) is administered to the silkworms and/or the silkworms are brought into contact with such an amount.

Description

(54) METHOD OF INCREASING THE PRODUCTIVITY OF HARDWARE SILK

2 also nutrients, appetite stimulants, bactericides and other growth regulators. Such finished Moryt formulations exist in conventional forms of application and are prepared in the same manner by good mixing and / or grinding of the active substance with or with additives. The following forms of use are mainly used. Solid formulations: powdered preparations, chemicals for soil application, pellet pellets, granules (coated granules, impregnating granules, homogeneous granules). Liquid formulations: wettable powders, pastes and emulsions that form dispersions in water. The active substance can be introduced into the prepared feed forms (powdered granulate preparations, wettable powder, emulsion-forming concentrates, spray preparations). The following substances are used to obtain a) 5% and 6) 2% powdered drug, 4: a) active substance 5, talc 95, active substance 2, highly dispersed silicic acid 1, talc 97. The active substance is mixed with a filler and crushed. For the preparation of the granulate, the following substances are used: 4: active substance 5, epichlorohydrin 0.25, cetylyl polyethylene one ester 0.25, polyethylene glycol 3.5O, kaolin 91 (grain size 0.3-0.8 mm), the active substance is shifted with epichlorohydrin and dissolved in 6 hours of acetone, after which polyethylene glycol and cetyl polyglycol ether are added. The spray solution thus obtained is sprayed onto the kaolin and then the acetone is reduced in vacuo. For the preparation of a) 40%, b) and c) 25%, g) 1O% wetting with a well, the following components are used, 4: a) active substance 4O, sodium salt of ligninsulfonic acid 5, sodium salt of dibutylnaphthalenesulfonic acid 1, silicic acid 54.6) active matter 25, calcium ligninsulfonate 4.5, a mixture of Champagne chalk - oxystildellulose {l: l) j 1.9, dibugylnaphthalene sulfonate sodium 1.5, silicic acid 19.5, champagne chalk - hydroxycellose (1: 1) 19, kaolin 28.1, c) the active substance 25 / isooctylphenoxy-polyoxyethylene-atanol 2.5, a mixture of chalk Champagne - hydroxyethylcellulose (1: 1) 1.7, sodium aluminosilicate 8.3, infusor earth 16.5, kaolin 46, g) active substance 10, a mixture of sodium salts of saturated sulfates of a fatty alcohol, 3, naphthalene sulfonic acid / formaldehyde condensate 5, kaolin 82, the active substance moves well in appropriate mixers with additives: and ground in suitable mills. Wetting sprinkles are obtained which can be diluted with water to a suspension of any desired concentration,. The following substances are used for the curing of a) and a) 10% - b) 25% and c) 5O% emulsifying concentrate; 4; a) active substance 10, epoxidized vegetable oil 3.4, a combined emulsifier consisting of polyglycolic ether of fatty alcohol and potassium salt alkylarylsulfonate 3,4, dimethylformamide 40, xylene 43.2, b) active substance 25, epoxidized vegetable oil, mixture of alkylaryl sulfonate- polyglycol ether of fatty alcohol 10, dimethylformamide 5, xylene 57.5, c) active substance 50, tributylphenol-polyglycol ether 4.2, calcium dodecylbenzenesulfonate 5.8, cyclohexacon 2.0. xylene 20. Of these concentrates, dilutions with water can produce emulsions of any desired concentration. To release a) 5% and b) 95% preparation, the following components are used for spraying, 4-. a) active substance 4, epichlorohydrin 1, gasoline (boiling range 160-190 ° C) 9-}, b) active substance 95, epichlorohydrin 5. The working amount of the active substance can vary in the range of fossil limits and is, as a rule, 0.1 and ZOO mkg, mainly between O, 1 and 100 mkg, and especially between 0.1 and 1 O mcg per larva The active substance has both a contact and an intestinal effect, which is manifested depending on the composition and type of application. The moment of use is predominantly chosen so that the active substance can develop its effect between the first and third day after the onset of the 5th larval stages, especially between the second and third day. The active substance can be applied OD1-1 once or several times over a period of six days, preferably three days.
