New Insights into the Interactions between Herbicides: Trends from Recent Studies

Area of Science:

• Agricultural Science
• Plant Science
• Ecology

Background:

• Herbicide combinations are widely used in agriculture.
• Weed and herbicide diversity can lead to unpredictable interaction outcomes.
• A predictive strategy is needed for optimizing herbicide mixtures.

Purpose of the Study:

• To develop a predictive strategy for herbicide interactions.
• To analyze herbicide and weed attributes influencing interaction outcomes.
• To identify herbicides that are promising or inadequate for beneficial mixtures.

Main Methods:

• Compiled a dataset from recent studies on herbicide combinations.
• Included attributes of herbicides (active ingredient, chemical family, mode of action).
• Included attributes of weeds (species, clade, leaf type, family, lifespan).

Main Results:

• Additive interactions (46.30%) were more frequent than antagonistic (29.09%) and synergistic (24.61%) interactions globally.
• Discussed the occurrence of interactions based on herbicide and weed features.
• Identified mesotrione as a promising herbicide and glyphosate as inadequate for predicting beneficial mixtures.

Conclusions:

• Herbicide-weed interactions exhibit a global trend that can guide farmers.
• Understanding interaction patterns aids in selecting effective herbicide companions.
• The study provides insights for optimizing herbicide use in agriculture.
