The present invention relates to herbicidal) active pyridyl-/pyrimidyl-pyrazine derivatives, as well as to processes and intermediates used for the preparation of such derivatives. The invention further extends to herbicidal compositions comprising such derivatives, as well as to the use of such compounds and compositions in controlling undesirable plant growth: in particular the use in controlling weeds, in crops of useful plants.

Provided herein is a method of reducing a microbial infection of a heparinized surface wherein heparin precipitation is reduced as compared to a control. In some embodiments a composition comprising ethanol and isopropanol is applied to the surface. In other embodiments, two or more ethanol compositions are applied and removed sequentially from the surface prior to contacting the surface with a biological fluid, tissue or vessel, wherein the composition in each successive administration comprises an increased amount of ethanol. Also provided is a method of reducing a microbial infection of a surface comprising applying a mucilage extract from an Opuntia ficus indica species to the surface.

A non-toxic unitary lice deterring and preventive headband is worn upon the scalp of a wearer. The headband does not use coatings or removable strips, or other reservoirs attached to the headband. The aromatic essential oils are preferably a 1.65% mixture by weight of citronella oil, rosemary oil, lemongrass oil and geranium oil, where the mixture is infused by further admixing in a resin of the styrene butadiene copolymer in an amount of 98.55% by weight. The raw plastic resin material, such as styrene butadiene copolymer, is first premixed and preheated into a malleable, pourable state, which is then admixed with the mixture of aromatic essential oils. The admixture of the plastic resin and aromatic essential oils is then injected into a headband-shaped mold The molded, admixed material is already prepared with lice deterring aromatic essential oils, when the molded, admixed plastic material is molded into a headband shape.
