摘要:
An insect repellent including a liquid system containing DEET and a fragrance oil which acts as a carrier for dispersing DEET vapor into the atmosphere upon evaporation of the fragrance oil. In one embodiment of the invention, the liquid system is contained within a solid thermoplastic system which can be formed as pellets for fabricating utilitarian products, e.g., wristbands and tablecloths. In another embodiment of the invention, the liquid system is contained within the wax of a candle which can be burned to emit DEET vapor into the atmosphere. In a third embodiment, the liquid system can be mixed with alcohol, with or without water, and dispersed by an air-wick to repel insects. In a fourth embodiment, towelettes can be soaked in the liquid system for later use as applicators of the liquid system to areas of the skin from which Deet vapor can be released into the atmosphere for effectively repelling insects from around the entire body.

Compatibility agents were developed for improving the compatibility and stability of mixtures of liquid fertilizers and liquid or wettable powdered pesticides. These compatibility agents contain water, a low alkanol and an alkylaryl polyoxyethylene glycol phosphate ester. The compatibility agent is used at a preferred concentration range of 0.1 to 0.4% of the fertilizer solution. The preferred compatibility agent not only improves the compatibility of liquid fertilizer-pesticide mixtures, but also results in uniform and stable mixtures ensuring accurate pesticide applications. The preferred compatibility agent is a mixture containing about 16% water, about 20% methanol and about 64% of an octylphenol polyoxyethylene glycol phosphate ester.

摘要:
A disinfectant composition is made with three essential active ingredients comprising (1) a quaternary ammonium compound, (2) a phenol or a derivative thereof, and (3) formaldehyde. The composition provides enhanced disinfecting efficacy of a synergistic nature, since the composition is more inhibitory and/or lethal to a greater variety of bacteria than is any one of its components or the sum of the separate effects of its components.
摘要:
The invention provides herbicidal compositions containing as active ingredients (1) a 1,2,4-triazin-5-(4H)-one derivative of the general formula ##STR1## in which R is amino or isobutylideneamino, and (2) a phenoxyalkanecarboxylic acid of the general formula ##STR2## in which X is methylene or methylmethylene,R.sub.1 is chlorine or methyl andR.sub.2 is hydrogen or chlorine,Which may be in the form of a salt or ester thereof, alone or in admixture with a solid or liquid or liquefied gaseous diluent or carrier;Which combinations provide synergistic weed-killing action against a wide range of weeds in cereals.
