Abstract: 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.

Abstract: 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.
