摘要:
The invention relates to fungicidal plant protecting composition comprising 3-90% by weight of a fungicidal active ingredient in admixture with 1-90% by weight of cyclodextrin and optionally with usual auxiliary agents.The advantage of the synergistic composition of the present invention is that identical fungicidal effect can be achieved with a significantly lower active ingredient dosage and this decreases the costs involved with the active ingredient and reduces the risks of environmental pollution as well.
摘要:
The invention relates to a process for the production of propagating material of plants by micropropagation in sterile tissue culture which comprises(a) planting sterile shoot cuttings of plants in solid nutrient medium in a suitable flask, filling up the flask with a suitable liquid nutrient medium optionally containing a growth regulator and growing the shoots in the submersed system; thereafter(b) cutting up into pieces the ramified culture thus obtained which contains a number of lateral buds and shoots, rooting the top-end shoots and planting the same after adaptation, and subjecting the cuttings prepared from the lower and middle parts of the shoot cultures to further cultivations according to step (a);and repeating steps (a) and (b) until the desired number of top-end shoots is reached.
摘要:
The invention relates to new phenanthrene derivatives wherein R stand for C.sub.1-10 alkylamino; C.sub.1-10 alkylthio; C.sub.1-5 alkoxy; or phenyl or phenylamino, the two latter groups being optionally substituted on the phenyl ring by one or more identical or different C.sub.1-4 alkyl, C.sub.1-4 alkoxy, nitro, amino, cyano and/or halogen substituent(s) .The compounds of the present invention possess valuable fungicidal properties and may be used in agriculture, horticulture and therapy as active ingredient of fungicidal or antifungal compositions.The compounds of the general Formula I ##STR1## may be prepared by acylating 9,10-phenanthrene-dione-9-oxime or an alkali or alkali earth metal salt thereof.
