Improved herbicide efficacy for organically grown vegetables

Organic Agriculture, 2015
Natural weed control alternatives that are currently approved for organic crop production are mostly nonselective essential oils used as postemergence, burn-down products. Their low efficacy requires multiple applications of high volumes to achieve good weed control.

Guideline for the efficacy evaluation of herbicides

EPPO Bulletin, 1989
The biological evaluation of a herbicide involves a programme of trials for assessment of efficacy in weed control and of selectivity to the crop. Trials may be used for efficacy evaluation or selectivity evaluation according to weed occurrence, provided the conditions specified in the guideline are satisfied.This guideline gives detailed instructions ...

Droplet size and physicochemical property effects on herbicide efficacy of pre-emergence herbicides in soybean (Glycine max (L.) Merr).

Pest Management Science, 2020
BACKGROUND Unlike post-emergence herbicides, little is known about droplet size effect on pre-emergence herbicide (PRE) efficacy. Four nozzle types were used to apply different PRE herbicides on eight soybean fields in Missouri and Mississippi in 2017 ...

Quantifying the detrimental effect of airborne dust on herbicide efficacy

, 2020
One side effect of human activity and global climatic change is more airborne dust. This not only has undesirable effects on human health and the environment, but may also adversely affect many agricultural processes, including herbicide efficacy.

Efficacy of Post Emergence Herbicides in Groundnut

LEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2020
Background: Groundnut encounters severe infestation of weed especially during the early stages of growth due to less crop canopy which allows higher weeds growth and thus crop becomes more susceptible to weed competition. During rainy season, effective and economical weed control is not possible through manual and mechanical weeding due to unfavorable ...
