Definitions

• This invention relates to compositions with useful fungicidal properties.
• the present invention provides a fungicidal composition
• a fungicidal composition comprising a) propamocarb or an acid addition salt thereof and b) ofurace.
• Propamocarb is a known fungicide and is the common name for propyl 3-(dimethylamino)propylcarbamate. It is usually sold as the hydrochloride salt.
• Ofurace is a known fungicide and is the common name for ⁇ -2-chloro- N-2,6-xylylacetamido- ⁇ -butyrolactone.
• compositions of the invention have advantageous properties over the individual components and that synergism is often demonstrated, and yield of crop may be increased.
• the ratios of the propamocarb to ofurace vary over a wide range but are usually in the range 20: 1 to 1 : 1 , preferably 10: 1 to 2: 1 . These ratios are based on the weight of the free base.
• pesticides may be employed in conjunction with the active ingredients described above providing they do not adversely affect the interaction between the fungicidal components.
• additional fungicides such as mancozeb, chlorothalonil, folpet, cymoxanil, captafol, maneb or zineb, which extend the range of activity in order to control a wider spectrum of fungi.
• compositions of the invention are active against a wide range of fungi, and especially phycomycetes such as Plasmopara spp, e.g. Plasmopara viticola, Phytophthora spp. , e.g. Phytophthora infestans and Pythium spp..
• phycomycetes such as Plasmopara spp, e.g. Plasmopara viticola, Phytophthora spp. , e.g. Phytophthora infestans and Pythium spp..
• Crops that may be treated include for example, potatoes, tomatoes, vines, lettuce, hops, ornamentals, tobacco, strawberries, including seeds, bulbs and tubers.
• compositions of the invention may be employed in many forms and are often most conveniently prepared immediately prior to use by mixing the ingredients in their commercially available form, if necessary in a quantity of water.
• compositions containing propamocarb and ofurace may be formulated into a concentrate or in a ready for use form.
• Suitable concentrates are generally those known the art for the formulation of agrochemicals, for example, a solution, a dispersion, an aqueous emulsion, a dispersible powder, an emulsifiable concentrate or granules.
• the concentration of the active ingredients (when used as the sole active components) in a composition for direct application to the crop by conventional methods is preferably within the range of 0.01 to 1 0 per cent by weight of the composition, especially 0.005 to 5 per cent by weight, but more concentrated compositions containing up to 40 per cent may be desirable.
• composition of the invention can be applied directly to plants by, for example, spraying either at the time which the fungus has begun to appear on the plant or before the appearance of fungus, as a protective measure.
• a suitable rate of application of the propamocarb is from 0.1 to 3 kilograms per hectare, preferably from 0.3 to 2.0 kilogram per hectare.
• the invention thus includes a method for controlling a phytopathogenic fungus which comprises applying to seeds, plants and other vegetative material or their habitat a) propamocarb or an acid addition salt thereof and b) ofurace, components (a) and (b) being applied either together or in sequence.
• a phytopathogenic fungus which comprises applying to seeds, plants and other vegetative material or their habitat a) propamocarb or an acid addition salt thereof and b) ofurace, components (a) and (b) being applied either together or in sequence.
• Potatoes plants were sprayed with appropriately diluted commercially available formulations of propamocarb hydrochloride and ofurace and mixtures of these. Ten replicates were used for each treatment. 24 Hours after treatment were then inoculated with Phytophthora infestans and kept under controlled environment conditions suitable for maintaining plant growth and development of the disease. After an appropriate time, the degree of infection of the leaf surface was visually estimated.
• a wettable powder composition suitable for use after dilution with water was made up by mixing the following components.
