of a polymerization initiator, may be prepared by heating the monomer in the presence of a chain transfer agent, stopping the polymerization by cooling when the reaction mixture has a bulk viscosity of 0,5 to 50 poises and the polymer an inherent viscosity of 0,25 to 1, and by using a ...
Downy Mildew of Grape (Plasmopara viticola - PLASVI) (24 Hour Protectant): Vines (cultivar Carignane) were grown from seed in a soilless peat-based potting mixture ("Metromix") until the seedlings were 10-20 cm tall. These plants were then sprayed to run-off with the test compound at ...

of isocyanate groups to total hydroxyl groups and secondary amine groups in the reaction mixture is about 0.85 to 2.2:1. The percentage of secondary-tertiary diamine in the diamine component is about 1 to 10%, based on the weight of the diamine component. In preferred embodiments of the ...
Fruhstorfer (1952) used a 1:1 mixture of granulated clay and peat to formulate his ‘Einheitserde’ compost. Dempster (1958) recommended 10% by volume of clay to 40% peat and 50% sand, whilst Danhardt and Kukle (1959) reported a progressive increase in growth as the amount of clay...
The invention relates to a process for processing soil in which beet have been grown to give high-quality potting compound by mixing the soil in which beet have been grown with organic substances and a granular substance, such as gravel, and composting the mixture, it also being possible for...
