The invention provides a concentrate for dilution with water in the preparation of an agriculatural composition for application to crops, soil or animals and comprising an agricultural chemical whose agricultural activity varies with the pH of the water; and the invention provides a method of preparing such agricultural composition by mixing the concentrate with water and effecting such pH modification to the composition as is necessary to obtain a pH in the composition at which the agricultural activity of the chemical is acceptable. The concentrate comprises an active ingredient and a pH indicator for colouring the water, and the proportions of pH indicator and active ingredient are selected so that when the concentrate is diluted with water to provide an effective concentration of active ingredient in the water, the pH indicator indicates visually whether or not the pH of the water is suitable for acceptable agricultural activiy of the chemical.
A concentrate comprising a mixture of a pH indicator for coloring water, an agricultural chemical for application to crops, soil or animals, and a pH modifying agent for modifying pH of water with which the concentrate is diluted, the agricultural chemical having an activity that varies with the pH of the water and having an acceptable agricultural activity at a pH within the range of 4-6, wherein the proportions of pH modifying agent, pH indicator and agricultural chemical in the concentrate are such that, when the concentrate is diluted with water to provide an effective concentration of the agricultural chemical and the pH of the water is modified by the pH modifying agent, the pH indicator indicates visually when the pH of the water is in the range of 4-6.
A process for preparing an agricultural composition which is suitable for application to crops, soil or animals, comprising:
