The present invention generally relates to non-aqueous solutions of plant growth regulator(s) and polar and/or semi-polar organic solvent(s), methods for making said non-aqueous solution, and methods for improving the growth and crop productivity of plants using said non-aqueous solution.

Non-aqueous solution of plant-growth regulator(s) and polar and/or semi-polar organic solvent(s)

A synergistic agricultural formula including at least one diacyl or diaryl urea, such as a N,N'-diformylurea, and at least one mixture of nutrients, such as a mixture of micronutrients and/or macronutrients. This synergistic agricultural formula gives those skilled in the art the ability to regulate important phenotypical parameters that lead to a variety of important agronomic and horticulture traits which improve crop yield parameters leading beyond that of its individual components.

The present invention is directed to a flowable mixture including: a) a hydrated clay suspension and b) sulfur derived from elemental sulfur. Preferably, the flowable mixture includes elemental sulfur particles and a hydrated, absorbent clay, such as bentonite clay. The flowable mixture is preferably a liquid mixture for use as a fertilizer or fungicide.

A synergistic agricultural formula including at least one diacyl or diaryl urea, such as a N,N'-diformylurea, and at least metal complex, such as metal complexes of cobalt, nickel, silver or other metals, is applied to plants at physiologically sensitive times resulting in prolonged and complete ethylene reduction. This synergistic agricultural formula gives those skilled in the art the ability to regulate important phenotypical parameters that lead to a variety of important agronomic and horticulture traits which improve crop yield parameters leading beyond that of its individual components.

The invention relates generally to a liquid solution formulation including gibberellic acid ('GA'), gibberellin('GA'), gibberellin(&#x201c;GA&#x201d;), or combinations thereof, and a low-volatile, organic solvent, and methods of their use. Specifically, the liquid solution formulations of the present invention are directed toward agricultural liquid solution formulations including at least one gibberellin and a low-volatile, organic solvent selected from polyethylene glycol, propylene glycol, and/or a non-polymeric glycol.

The present invention is directed to a method for enhancing the rate of formation of the reaction products of a carboxylic acid and a urea having the formula: where R, R, Rand Rare the same or different and are selected from the group consisting of hydrogen, substituted and unsubstituted alkyl, allyl, vinyl and alkoxyl groups having from 1-6 carbon atoms, substituted and unsubstituted phenyl groups and the halides. The rate of formation is enhanced by adding acid to a solution including the carboxylic acid and the urea. Preferably, the reaction product of the present invention is N,N'-diformylurea or N,N&#x2032;-diacetylurea. These reaction products, e.g., diformylurea, have been found to produce significantly improved growth in a variety of agricultural products when applied to the seed, to the surrounding soil or to the foliage of the emerging plant.

A plant growth enhancing mixture and method of application applied exogenously very early in crop establishment, as a seed treatment, or in the seed furrow or into the soil for the roots of crop plants, in the right proportions, result in a root pattern that has very deep and strong rooting with a distinct minimal of profuse proliferation of lateral roots close to the soil surface, having numerous benefits as well as preferred, in situ, plant auxin transport and heightened drought tolerance.

It has been discovered that applying diformylurea (DFU) to seed of crop plants enhances the feeder root capability of the plants to take up water and minerals from the soil environment. A further discovery is that crop plant cellular water and soil maintenance around feeder roots is increased by applying DFU to crop seeds prior to planting, to the soil surrounding the plants or to foliage of the plants. A still further discovery is that crop plant drowning is prevented when flooded by excessive rain or other types of flooding. A still further discovery is that crop plant yields are enhanced by combining DFU and nitrogen fertilizer to the soil of the crop plants.

Methods for applying diformylurea to crops for greater plant productivity

A composition and method to mitigate plant autophagy and/or apoptosis of newly developing cells in plants grown under environmentally stressful growing conditions, such as high temperature. Exogenous application of a cytokinin, preferably kinetin, to either the roots or the foliage (i.e., flowers and leaves) of plants has been discovered to overcome, or at least substantially mitigate, autophagy when applied during or just prior to flowering. Experimental results indicate that high temperature-induced autophagy, and subsequent new cell apoptosis, is the result of a deficiency of cytokinin in the plant tissues. The application of low concentrations of potassium together with the cytokinin appears to provide a synergistic effect by amplifying the effect of the cytokinin to lessen autophagy and increase crop productivity.

Composition and method for stress mitigation in plants

The present invention is directed to methods for inhibiting the growth of disease organisms, particularly fungi and bacteria, on plant tissues. The present invention is also directed to methods for inhibiting the infestation of plants by insects and larva, particularly sucking and chewing insects. These methods are achieved by applying an auxin or a plant growth regulator (PGR) which will effect the level of auxin in the plant tissue to the seeds or tubers of the plant prior to planting or to the roots, foliage, flowers or fruit of the plant after planting.

Controlling plant pathogens and pests with applied or induced auxins

In agriculture when temperature and moisture deviate from the norm two things happen, plant growth suffers and disease flourishes. The Stoller model for plant growth states that proper hormone balance is necessary for optimum growth and performance. When growth conditions deviate from the norm, hormone balance is altered and plant growth suffers. This invention presents evidence to support this model and explain the relationship between hormone levels and plant growth. A clear understanding of this relationship will facilitate crop treatments aimed to eliminate these problems. Although we cannot control the climate, we can control the damage caused by environmental stresses by manipulating the levels and/or ratio of plant hormones in the different plant tissues. By adjusting the levels and/or ratios of hormones, particularly auxin and cytokinins in the root tissue, we can assist the plant in overcoming or compensating for this environmental stress.

Methods for improving growth and crop productivity of plants by adjusting plant hormone levels, ratios and/or co-factors

The present invention is directed to a method of inhibiting the growth of disease organisms on and in plants by directly applying an aqueous solution comprising urea and at least one water-soluble salt of a divalent cation and a monovalent anion to the seeds, stems, bark, leaves, seed heads or sub-surface root zones of said plants. The weight percent ratio of urea to divalent cation in these solutions should be from about 0.25-10.0 to 1.0. Preferred divalent cations include those of the alkaline earth metals and the transition metals. Most preferred are calcium, magnesium, zinc, manganese, copper, iron, cobalt, nickel and mixtures thereof. Preferred anions include nitrate, chloride, bromide and mixtures thereof. In more preferred solutions, the ratio of urea to divalent cation is from about 2.0-7.0 to 1.0. Particularly preferred solutions include calcium chloride as the water-soluble salt. Optionally, a second water-soluble salt of a divalent cation and a monovalent anion may be included.
