Abstract: The mixture of certain amine salts of glyphosate and 2,4-D allows the preparation of high-strength liquid compositions containing up to greater than 450 gae/L of total active ingredient loading if the pH is adjusted to about 6.0 to about 8.0. Compositions are particularly well-suited for application to crops that are resistant or tolerant to both glyphosate and 2,4-D.

Abstract: A method for promoting germination of underground buds and growth of new-born root systems of ratoon sugarcane is to cut stubbles based on a depth survey of the stubbles of the ratoon sugarcane, particularly including steps of: for a ratoon sugarcane field after mechanical harvesting, cutting the stubbles with a sugarcane stubble cutting machine, and remaining underground stubbles of 5-7 cm after cutting; for a ratoon sugarcane field with manual harvesting, cutting the sugarcane with a hoe, and remaining underground stubbles of 10-12 cm after cutting, so as to realize sugarcane cutting and stubble cutting in one step; thereafter, applying fertilizers and pesticides, and hilling up, wherein the underground buds of the stubbles are controlled to be distributed 10-15 cm below ground after hilling up; and finally conducting whole film mulching. The present invention is advanced and practical, and easily used and promoted.

Abstract: The present invention provides a concentrate for dilution with water in the preparation of an agricultural composition for application to crops, soil or animals. The concentrate is recommended for use with agricultural chemicals whose agricultural activity varies with the pH of the water. It comprises an active ingredient and a combination of pH indicators for coloring the water, the pH indicators being selected so as to indicate different colors of spray water at different pH levels. The proportions of active ingredient and pH indicators are selected so that when the concentrate is added to water, the pH indicators indicate visually upper and lower pH limits for optimum activity of the agricultural chemical.

Abstract: It has been shown that the formulation of phosphonic compound (ethephon) with sulfuric acid increases the efficacy and efficiency of ethephon and the speed of the effect of the ethephon. It was theorized that the effect that is shown by the mixture of ethephon and sulfuric acid could be achieved using another acid. The effect was demonstrated using muratic acid. All acids that reduce the pH of the spray carrier are claimed in this patent as synergist for phosphonic acid compounds such as ethephon.

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: 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: A method of defoliating plants includes applying to plants an effective amount of a first active ingredient selected from the group consisting of substituted nitroguanidine and cyanoguanidine compounds of the formula: wherein R1 is NO2 or CN; R2 is CH3, C2 H5, CF3, n-C3 H7, CH2 OCH3 or CH2CH═CH2; X is hydrogen, o-F, m-F, p-F, m-OCH3, m-OH or p-Cl; and the salts, tautomers and optical isomers thereof; an effective amount of a second active ingredient and optionally, an adjuvant.

Abstract: Concurrent or sequential application of an auxin transport inhibitor and a defoliating agent synergistically improve defoliation of crop plants and minimize crop plant regrowth. Preferably, the auxin transport inhibitor is a semicarbazone compound. The defoliating agent may be an ethylene response or ethylene-type response agent such as a phosphonic acid derivative. Most preferably, the semicarbazone compound is diflufenzopyr and the phosphonic acid derivative is ethephon (i.e., ethephon (2-chloroethyl) phosphonic acid).
