... explanation for the decreases in D90 observed after elevated temperature storage is that the addition of heat energy drove the particle surface area toward equilibrium according to the equation Δ A = W ∕γ, where Δ A is change in surface area, W is work, and γ is interfacial tension herbicide EW...

... Glyphosate is a broad-spectrum herbicide effective on deep-rooted perennial species and on annual and biennial species of grasses, sedges, and broadleaf weeds. The solubility of glyphosate acid is relatively low in water, 12 g/L (25°C). Since glyphosate is an acid, however, numerous water...

... N-phosphonomethylglycine (glyphosate) is firmly established as the preeminent herbicide of choice in a wide range of applications for the crop protection industry. It is well known that the efficacy of glyphosate can be enhanced with the use of surfactant adjuvants. Surfactants based on amine...

... Glyphosate, discovered by Monsanto's Dr. John E. Franz in 1970, has become one of the most environmentally friendly and commercially successful herbicides in the world. Glyphosate was the result of a program at Monsanto to find a herbicide that would control perennial weeds. This narrative...

... Adjuvant effects on weed control by diuron (N'-3,4-dichlorophenyl)- N,N -dimethylurea) and norflurazon [4-chloro-5-(methylamino)-2-(3-(trifluoromethyl)phenyl)-3(2 H )-pyridazinone] were studied to explore the potential of adjuvants in enhancing activity of soil-applied herbicides and to examine...

... With the advent of glyphosate-resistant crop seed, glyphosate has become the herbicide of choice for controlling weeds in a wide range of field crops. Many manufacturers of agricultural chemicals are adding glyphosate herbicides to their herbicide product lines to serve this market need...

...-acres of corn and 39.5 million acres of cotton. Herbicides were applied annually to 173.7 million acres of corn, 34.9 million acres of cotton and 147.7 million acres of soybean. After seed becomes fully available, B.t. corn is predicted to be seeded on 40% of the acres and B.t. cotton on 75...

... The literature on the effects of active ingredients, adjuvants and surface active agents on the droplet size of agricultural sprays is reviewed. The effects of various agricultural adjuvants on the droplet size distributions of a herbicide sprayed in a wind tunnel simulating an aerial...

... Specific dearomatized hydrocarbon fractions with boiling ranges between 220 and 310°C can significantly increase the performance of active ingredients in certain herbicides, fungicides and insecticides when they are incorporated, in combination with surfactants, in the formulations (co-adjuvants...

... The adjuvant can influence the performance of the herbicide. The use of sugar ether based adjuvants in greenhouse trials in combination with two sugar beet herbicides Betanal Compact (*) (Phenmedipham - Desmedipham EC) and Goltix WG (*) (Metamitron WG) resulted in a superior weed control when...

Solvents tested differed in relative wax solubility and in their affect on leaf-cell membrane permeability, but no obvious relationship occurred among these factors and the absorption, translocation and phytotoxicity of fluazifop-P. carrier corn fluazifop-P green foxtail herbicide adjuvancy...

... Sorghum and pinto bean plants were used as indicator organisms in a 14-day laboratory test to determine the impact of fuel and herbicide spills in agroecosystems. Plant survival and shoot length (from soil level to tip of highest leaf) were recorded and compared for plants grown in laboratory...

... Bioassays utilizing the green alga Selenastrum capricornutum were performed on filtered eluates from soil treated with six commonly used forestry herbicides applied at labelrecommended rates. The bioassays were conducted at three time periods after herbicide application—one hour, five days...
