Ra represents a hydrogen atom, a hydroxy group or a monovalent organic group having 1 to 20 carbon atoms, and optionally taken together represents a ring structure by binding with R each other. A? represents —SO3? or —CO2?. M+ represents a monovalent onium cation.

Abstract: The invention relates to compositions useful in the field of agricultural chemistry and methods for making and using the compositions. The compositions include (i) a permeabilizing agent, and (ii) a active component, for example, a pesticide or plant growth regulator, and can include additional components as well, for example, flow agents. The permeabilizing agent, or a mixture of permeabilizing agents, acts as an adjuvant to the active component or chemicals to improve the degree of efficacy of the active component or speed of action of the active component. The permeabilizing agents are typically one or more chelating agents, cationic materials, anionic materials, and zwitterionic materials, and include polyphosphate salts. Examples of cationic materials include polyamines such as ethylenediamine and quaternary ammonium salts. The active components can be pesticides, herbicides, insecticides, fungicides, virucides, bacteriocides, and acaricides.

Abstract: The present invention includes an aqueous solution, comprising boric acid and non-colloidal silicic acid. This solution can also comprise a water absorbing additive. The solution contains bioavailable non-colloidal silicic acid, and the solution is stable for more than one year. The invention also describes a method for the preparation of a solution in which one or more silicon and boron compounds are hydrolysed in an acidic solution containing one or more dissolved water absorbing additives.

Abstract: A systemic inducer for inducing resistance to nematode infestation comprising a nutrient combined with microorganism substance extracted from microorganisms. The nutrient or fertilizer includes at least a phosphoric acid, and the salts thereof, a phosphorous acid and the salts thereof, or the salts of phosphorus, potassium, calcium, sodium, magnesium, manganese, zinc, copper and iron. The microorganism substance may be extracted from fungus, bacteria or virus. The systemic inducer may be applied to stems and leaves of plants. Alternatively, the systemic inducer may be applied to soil to elicit a response via the roots of the plants. Finally, the systemic inducer may be injected into the stem or pseudo stem of the plants.

Abstract: An indicating desiccant comprises a silica-based material having impregnated thereon a source of copper and a source of bromide, the source of copper being present in an amount up to 0.5 per cent by weight, calculated as Cu with respect to weight of the silica-based material, and the source of bromide being present in an amount such that the weight ration of Br to Cu is at least 5:1. Optionally, the indicating desiccant also comprises a dye or other coloured material.

Abstract: A method of treating plants to raise their resistance to viroids and to protect them from the effects of viroid infections by administering bioassimilable boron compounds to the plants.

Abstract: A solid, water-soluble complex comprising:a) a water-miscible polysiloxane of the formula: ##STR1## wherein n is from 2 to 6; a is from 8 to 25; and b is from 0 to 25; and the oxyalkylene groups may be random or block mixtures; y is from 0 to 5; x is from 1 to 5; and R is selected from the group consisting of hydrogen, C.sub.1- C.sub.4 alkyl, and a C.sub.1- C.sub.4, alkyl ester; or ##STR2## wherein A is a linear or branched alkyl having 6 to 30 carbon atoms; G is a glycol moiety of the formula --R' (OCH.sub.2 CH.sub.2) .sub.m OR" wherein R' is a divalent alkylene group having 2 to 6 carbon atoms; R" is selected from the group consisting of hydrogen, C.sub.1- C.sub.4 alkyl, and a C.sub.1- C.sub.4 alkyl ester; m is 8 to 100; y is 0 to 5; X is 0.1 to 2.5; and z is 0.1 to 5.0; andb) a complex-forming agent of the formula: ##STR3## wherein X is O, S, Sc, or Te. These complexes are useful useful as adjuvants for dry agricultural chemicals such as pesticides and/or fertilizers.

Abstract: There is disclosed a method of desiccating potato vines. The method comprises applying to potato vines an effective amount of an aqueous solution of a copper-alkylenediamine complex, such as a copper-ethylenediamine complex.
