Effect of Nozzle Selection and Spray Volume on Droplet Size and Efficacy of Engenia Tank-Mix Combinations
Sprayer applicator-controlled variables, such as nozzle selection and spray volume, will become increasingly important for making labeled POST applications of dicamba in next-generation croppingExpand
Liverwort (Marchantia Polymorpha) Control with Quinoclamine
Control was influenced primarily by quinoclamine rate, although there was a trend for greater control with higher spray pressure, and the perceived requirement for high spray volume may be a misdirected assumption. Expand
Effect of Venturi-Type Nozzles and Application Volume on Postemergence Herbicide Efficacy1
Abstract: Field studies were conducted to compare venturi-type nozzles to a fan nozzle with respect to the efficacy of postemergence herbicides applied to common cocklebur and broadleaf signalgrass.Expand
Junglerice control with glyphosate and clethodim as influenced by dicamba and 2,4-D mixtures
Abstract Junglerice has become a major weed in the mid-south and other areas of the United States. Glyphosate resistance has been documented in junglerice populations and is part of the reason forExpand
Effect of dicamba rate and application parameters on protoporphyrinogen oxidase inhibitor-resistant and -susceptible Palmer amaranth (Amaranthus palmeri) control
Results concur with those of other research that suggest PPO-resistant Palmer amaranth is harder to control with dicamba, and increasing carrier volume affected overall PalmerAmaranth control to a greater degree than any other factor. Expand
Corn ( Zea mays L.) response to sublethal rates of paraquat and fomesafen at vegetative growth stages
Corn response to sublethal paraquat or fomesafen applications near corn should be avoided if conditions are conducive for off-target movement, because significant injury and yield loss can result. Expand
Droplet Size Impact on Efficacy of a Dicamba-plus-Glyphosate Mixture
Abstract Chemical weed control remains a widely used component of integrated weed management strategies because of its cost-effectiveness and rapid removal of crop pests. Additionally,Expand
Droplet size and physicochemical property effects on herbicide efficacy of pre-emergence herbicides in soybean (Glycine max (L.) Merr).
It is indicated that droplet size does not affect PRE herbicide efficacy regardless of physicochemical herbicide properties including adsorption, volatility and solubility. Expand
Droplet size impact on lactofen and acifluorfen efficacy for Palmer amaranth (Amaranthus palmeri) control
Abstract Herbicide applications performed with pulse width modulation (PWM) sprayers to deliver specific spray droplet sizes could maintain product efficacy, minimize potential off-target movement,Expand


Droplet Size and Phytotoxicity of Herbicides1
An oil soluble formulation of the dodecyl (51% w/w) and the tetradecyl (13% w/w) amine salts of (2,4- dichlorophenoxy)acetic acid (2,4-D) was diluted with diesel oil and applied in homogeneous spraysExpand
The Measurement of Airborne Droplets by the Magnesium Oxide Method
A complete calibration has been made for the first time of the method of detecting and measuring airborne droplets whereby the permanent impressions made when they strike a layer of magnesium oxideExpand
