A novel method is provided wherein plants are first treated with an exogenous chemical (e.g., glyphosate herbicide) and then sequentially treated with a liquid accession agent which provides improved biological (e.g., herbicidal) effectiveness such that plants are controlled with lower rates of the applied exogenous chemical (e.g., glyphosate herbicide). Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that can be exhibited when the accession agent is added to a herbicide in a tank mix or simple coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain organosilicone-based and fluorocarbon-based surfactants.
A method of applying an exogenous chemical to a plant, comprising sequentially the steps of (a) contacting foliage of the plant with a biologically effective amount of an exogenous chemical composition, and (b) thereafter contacting at least a part of the same foliage of the plant with an accession agent, whereby antagonism to biological effectiveness that would be exhibited were the plant contacted with a tank mix or a simple coformulation of the exogenous chemical and the accession agent is substantially reduced.
A method of applying an exogenous chemical to a plant, comprising sequentially the steps of (a) contacting foliage of a plant with a biologically effective amount of an exogenous chemical composition, and (b) thereafter contacting at least a part of the same foliage with an aqueous solution or dispersion of an anionic surfactant.
A method of applying an exogenous chemical to a plant, comprising sequentially the steps of (a) contacting foliage of the plant with a biologically effective amount of an exogenous chemical composition, and (b) thereafter contacting at least a part of the same foliage of the plant with an accession agent, wherein the exogenous chemical and the accession agent are contacted with one or more plants selected from the group consisting of:
A method of applying a herbicide to a plant, comprising sequentially the steps of (a) contacting foliage of the plant with a herbicidally effective amount of a herbicide composition, and (b) thereafter contacting at least a part of the same foliage of the plant with an accession agent, whereby ultimate herbicidal inhibition of the plant is substantially improved over that exhibited by contacting the plant with a tank mix or simple coformulation of the herbicide composition and the accession agent.
A herbicidal method comprising sequentially the steps of (a) contacting foliage of a plant with a herbicide comprising N-phosphonomethylglycine or a herbicidal derivative thereof and (b) thereafter contacting at least a part of the same foliage with an accession agent, whereby antagonism to herbicidal effectiveness that would be exhibited were the plant contacted with a tank mix or simple coformulation of the herbicide and the accession agent is substantially reduced.
A method for enhancing the herbicidal effectiveness of a herbicide for a plurality of plant species in a field comprising the steps of (a) applying to the foliage of the plurality of plant species a herbicide comprising N-phosphonomethylglycine or a herbicidal derivative thereof and (b) thereafter applying to the same foliage an accession agent, whereby the herbicidal effectiveness of the herbicide for at least one of the plurality of plant species is substantially enhanced.
A method for reducing the antagonism of an accession agent to the herbicidal effectiveness of a herbicide comprising N-phosphonomethylglycine or a herbicidal derivative thereof comprising the steps of (a) applying the herbicide to foliage of a plant species for which the accession agent is antagonistic to the herbicidal effectiveness of the herbicide when tank mixed therewith or admixed therewith in a simple coformulation and (b) thereafter applying to at least a part of the same foliage the accession agent, whereby the herbicidal effectiveness of the herbicide for the plant species is substantially preserved or enhanced.
A herbicidal method comprising sequentially the steps of (a) contacting foliage of a plant with a herbicide comprising a water soluble salt of N-phosphonomethylglycine and (b) thereafter contacting at least a part of the same foliage with an aqueous solution containing at least about 0.5% by weight or volume of a superwetting surfactant selected from the group consisting of organosilicone wetting agents and fluoro-organic wetting agents, whereby antagonism to herbicidal effectiveness that would be exhibited were the plant contacted with a tank mix or simple coformulation of the herbicide and the superwetting surfactant is substantially reduced.
A method for enhancing the herbicidal effectiveness of a glyphosate herbicide for a plurality of plant species in a field comprising the steps of (a) applying to foliage of the plurality of plant species in the field a herbicide comprising a water soluble salt of N-phosphonomethylglycine and (b) thereafter applying to the same foliage an aqueous solution containing at least about 0.5% by weight or volume of a superwetting surfactant selected from the group consisting of organosilicone wetting agents and fluoro-organic wetting agents, whereby the herbicidal effectiveness of the herbicide is substantially enhanced for at least one of the plurality of plant species.
A method for enhancing the yield of a field crop comprising the steps of:
A method of enhancing the yield of a field crop comprising the steps of:
A herbicidal method comprising sequentially the steps of (a) contacting foliage of a plant with a herbicide comprising dicamba or a herbicidal derivative thereof and (b) thereafter contacting at least a part of the same foliage with an accession agent.
A method of applying an exogenous chemical to a plant, comprising sequentially the steps of (a) contacting foliage of the plant with a biologically effective amount of an exogenous chemical composition, and (b) thereafter contacting at least a part of the same foliage of the plant with an aqueous solution or dispersion of a sulfonylamino compound having the formula
