... are lacking and outdated. This paper presents a new experimental paradigm for both characterizing and quantifying the spreading behavior of a liquid agricultural product through semi-automated goniometry. Method A overcomes the error and bias in traditional, single-valued contact angle measurements...

... Adjuvants are known to enhance spray droplet retention on leaf surfaces and penetration of herbicide active ingredients through cuticles due to changes in physical properties such as density, viscosity, surface tension (SFT), and contact angle (CA) increasing leaf wettability. However, previous...

... on spreading and longer times for evaporation overestimated spreading of the larger droplets on Parafilm M. If the mean spread diameters of real spray was plotted vs. the logtransformed spread diameter on Parafilm M a linear correlation was obtained ( r 2 = 0.92 ). adjuvants contact angle...

... for sealants applied in contact with self-cleaning glass (SCG). Our discussion here focuses on the possibilities of this particular application. SCG possesses a photocatalyst layer which enables two reactions, i.e., lessening the contact angle of the glass surface and decomposing organic compounds on the glass...

... Trifloxysulfuron 2.5, 5, and 10 g ai/ha mixed with non-ionic (0.25 % Induce and X-77), organosilicone (0.1 % Kinetic and Silwet L-77), and crop oil concentrate (1 % Agridex and Meth-N-Oil) adjuvants was evaluated for efficacy, surface tension (ST), contact angle (CA), and chlorophyll...

... tension and contact angle were measured under lab conditions. Adjuvants increased the activity of glyphosate by 15–29 % compared to glyphosate alone. Among the weed species, higher mortality was observed in P. maximum and B. pilosa followed by E. crus-galli and lowest in A. theophrasti...

... fluids on the wetting of Sorghum halepense (johnsongrass) and other model substrates has been investigated. The wetting properties, as measured by contact angle, of four different series of hydrocarbon fluids (normal paraffins, isoparaffins, mixed aliphatics containing iso-, cyclo- and normal paraffins...

... antagonism. Correlation of adjuvant physico-chemical properties and glyphosate efficacy was also analyzed. The results showed that contact angle and spreading coefficient had significant effect on glyphosate efficacy 1 week after treatment (WAT). As the time interval increased to 2, 3, and 4 WAT...

... The study was conducted to investigate the physico-chemical properties and the spread pattern on velvetleaf ( Abutilon theophrasti Medikus) foliage of several organosilicones, oil concentrates, nonionic adjuvants, and adjuvant mixtures. A dynamic contact angle analyzer, surface tensiometer...

A graph of the cosine of the spray droplet contact angle against the surface tension can be extrapolated to predict the surface tension necessary to achieve a zero contact angle (perfect wetting). Surfactants and emulsifiers typically used in pesticide formulations cannot reduce aqueous surface...
