This invention is based on unexpected effect of at least one thickener to maintain suspension or dispersion of solid particles in an oil medium. Such effect of thickener enables significant higher weight ratio of solid particles in such suspension composition as compared to previously known compositions. As a consequence, the suspension compositions provided herein enable more active ingredient in the solid particle to be present in a fixed volume or weight of such composition as compared to previously known compositions. One advantage of the suspension composition provided herein can be for aerial spraying of active ingredient such as herbicides, insecticides, or other growth regulating compounds.

Oil formulations with thickeners

Provided are methods of treating specific crop plants when those plants have reached specific developmental stages. Also provided is a method for improving the yield of a crop produced by a plurality of plants, which may or may not be any of the specific plants mentioned herein above, wherein said method comprises contacting said plants with at least one composition that comprises at least one cyclopropene.

Contacting crop plants with compositions

Provided is a composition comprising Also provided are methods of storing and using such compositions.

Cyclopropene compositions

A composition is provided that contains a cyclopropene and a metal-complexing agent. Also provided is a method that includes contacting such compositions to plants or plant parts.

Compositions with cyclopropenes and metal-complexing agents

There is provided a composition comprising an oil medium, wherein particles are suspended in said oil medium, wherein said particles comprise cyclopropene and molecular encapsulating agent, and wherein said particles have median size, as measured by the largest dimension, of 50 micrometer or less. Also provided are a method of making such a composition and a method of treating plants by contact with such a composition.

Oil formulations

The present invention relates to complexes formed from molecular encapsulation agents such as cyclodextrin, and cyclopropene and its derivatives such as methylcyclopropene, which are capable of inhibiting the ethylene response in plants. More specifically this invention relates to compositions of cyclopropenes and molecular encapsulation agents containing additives to improve the release of the cyclopropene when the composition is contacted with water.

Delivery system for cyclopropenes

The present invention relates to new delivery systems for cyclopropenes in which the cyclopropene, either free or encapsulated within a molecular encapsulation agent is incorporated into produce packaging materials.

Delivery systems for cyclopropenes

The present invention relates to a method to produce suspension concentrates of pesticides, pharmaceuticals, biocides, and similar materials, using a melt emulsification process. The method is particularly applicable to pesticides which have a low water solubility. The particle size can be controlled to give particles from less than 5 microns (&mgr;) to less than 1&mgr;.

Method to produce pesticide suspension concentrates

The present invention relates to complexes formed from molecular encapsulation agents such as cyclodextrin, and cyclopropene and its derivatives such as methylcyclopropene, which are capable of inhibiting the ethylene response in plants, wherein the complex is pressure agglomerated.

The present invention relates to new delivery systems for cyclopropenes in which compositions comprising the cyclopropene and a molecular encapsulation agent complex further comprise additional components which provide slow release of the cyclopropene from the molecular encapsulating agent with water, or release of the cyclopropene from the molecular encapsulating agent with only small amounts of water, or both. The present invention also provides methods to release a cyclopropene from such compositions as well as methods to deliver a cyclopropene compound to a plant to inhibit an ethylene response in the plant.

Delivery systems for cyclopropenes requiring less water

Titanium dioxide particles are dispersed in an aqueous medium with a polymeric latex which adsorbs to the surface of the titanium dioxide to give a low-viscosity slurry or pigment grind of composite titanium dioxide-polymeric latex particles. A high glass transition polymeric latex can be used as the dispersant, and a low glass transition temperature binder latex can be added. The zeta potential of the polymeric latex can be at least about 30 millivolts more negative than the zeta potential of the titanium dioxide. The adsorbed polymeric latex provides more optimal spacing of the titanium dioxide particles in films formed from coating compositions formulated using the composite particles, and consequently greater film opacity and hiding at a given pigment volume concentration. Coatings formulated using the composite particles can be prepared to give the same hiding as coatings including titanium dioxide dispersed with conventional polyelectrolyte pigment dispersants, but with lower levels of costly titanium dioxide. Alternatively, a single selected polymeric latex can be used to both strongly adsorb to the pigment particles and to serve as binder, or a mixture of a selected, strongly adsorbing polymeric latex having a low effective glass transition temperature and a conventional binder latex can be employed.

Process for preparing an aqueous dispersion of composite particles

This invention is relates to dithiocarbamate fungicide formulations having improved physical properties. The formulations comprise one or more dithiocarbamate fungicides and a water soluble polymer.

Dithiocarbamate fungicide compositions with improved properties

Inorganic material particles are dispersed in an aqueous medium with surface charge adjusting additives to give a moderately stable slurry or pigment grind. The dispersion can be used to prepare fully formulated compositions. Products formulated using the aqueous dispersion can be prepared to give the same performance as products including inorganic material dispersed with conventional polyelectrolyte pigment dispersants, but with higher levels of inorganic material, or superior performance properties with like levels of inorganic material.
