The disease first appears on leaves as tiny orange to reddish-brown flecks that enlarge to form raised pustules. Philanthropy & Alumni It occurs during the peak of hot weather when cool-season grasses are barely growing. If chemical control is necessary, the most effective fungicides contain azoxystrobin, azoxystrobin with propiconazole, or thiophanate-methyl and are available for use in the home lawn. At a few sites, fungicides were detected in all samples collected suggesting the potential for season-long occurrence in some streams.
Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicide as determined by labeled instructions and overall level of disease in the field at the time of application. Cookies. The amount of surfactants required to emulsify an oil will depend on the amount of oil in the emulsion, more specifically the interfacial surface area which is proportional to the amount of emulsified oil at a constant particle size. Microemulsions of any required dilution can be obtained from this concentrate by dilution with water and can be used, for example, in the protection and enhancement of the health, quality and productivity of useful plants and for the control of diseases (whether on agricultural, residential, commercial or public land). piperazine or tetrazines, Pyrimidines; Hydrogenated pyrimidines, e.g.

The disease first appears on leaves as tiny orange to reddish-brown flecks that enlarge to form raised pustules. Philanthropy & Alumni It occurs during the peak of hot weather when cool-season grasses are barely growing. If chemical control is necessary, the most effective fungicides contain azoxystrobin, azoxystrobin with propiconazole, or thiophanate-methyl and are available for use in the home lawn. At a few sites, fungicides were detected in all samples collected suggesting the potential for season-long occurrence in some streams.
Efficacy is based on proper application timing to achieve optimum effectiveness of the fungicide as determined by labeled instructions and overall level of disease in the field at the time of application. Cookies. The amount of surfactants required to emulsify an oil will depend on the amount of oil in the emulsion, more specifically the interfacial surface area which is proportional to the amount of emulsified oil at a constant particle size. Microemulsions of any required dilution can be obtained from this concentrate by dilution with water and can be used, for example, in the protection and enhancement of the health, quality and productivity of useful plants and for the control of diseases (whether on agricultural, residential, commercial or public land). piperazine or tetrazines, Pyrimidines; Hydrogenated pyrimidines, e.g.

The fungus, Claireedia homoeocarpa, is the cause of dollar spot in lawns. It is one object of the present invention to prepare microemulsifiable concentrates which, upon dilution, form liquid azoxystrobin microemulsion formulations having prolonged physical stability. It has been found that when microemulsifiable concentrates comprising azoxystrobin and propiconazole are diluted in a sufficient amount of water to form a microemulsion, the microemulsions exhibit enhanced physical stability compared to similarly formulated azoxystrobin emulsions which do not contain propiconazole; the novel compositions are storage stable, easy to apply, ecological and toxicologically favorable and, upon dilution with water, are useful as agrochemical compositions that have good biological efficacy in the target application and exhibit prolonged physical stability upon dilution in water.
