Effectiveness of using the mixtures of herbicides flumioxazine and fluorochloridone in sunflower crops
Aim. This work is devoted to the search for potential partners for the integrated application of flumioxazine in
sunflower crops. This herbicide is an inhibitor of protoporphyrinogen oxidase (PPO) in weed plants. The resistance
to this class of herbicides is not yet common today, compared to other classes. Therefore, the work is aimed at de-
veloping flumioxazine-based herbicide compositions that effectively prevent the emergence of herbicide-resistant
weed biotypes. Methods. The interaction effects, weed control efficiency, and crop selectivity were studied when
flumioxazine was used in the mixtures with herbicides acetochlor and propisochlor (long-chain fatty acid synthesis
(LCFAS) inhibitors), promethrin (electron transport (ET) inhibitor in photosystem 2 (PS 2) of chloroplasts) and
fluorochloridone (inhibitor of carotenoid synthesis by blocking the activity of phytoendesaturases (PDS)) both in
the experiments on sunflower crops and in greenhouse experiments using the model objects. Results. The studies
have shown that when flumioxazine is applied with the ET inhibitor, promethrin, the interaction is antagonistic,
resulting in poor weed control efficiency and sunflower yield decrease. The tank mixtures of flumioxazine with
LCFAS inhibitors acetochlor and propisochlor provide high weed control efficiency but are low in selectivity for
sunflowers. The interaction between flumioxazine and fluorochloridone within the recommended application rates
is additive. The tank mixture of flumioxazine and fluorochloridone herbicides at the application rates of 55 and 500
g/ha, respectively, is selective for sunflowers. In terms of control efficiency of annual dicotyledons, this mixture of
herbicides exceeded, and in terms of control efficiency of annual cereal weed species was only slightly inferior to
the control integrated herbicide (metolachlor + terbuthylazine). In these application rates, flumioxazine and fluo-
rochloridone provided sunflower yield on par with this complex herbicide. Сonclusions. Among the investigated
herbicides, the optimal partner of flumioxazine for complex use in sunflower crops was the herbicide, inhibitor
PDS, fluorochloridone. Given that flumioxazine and fluorochloridone differ in their phytotoxicity mechanisms
but share a common spectrum of controlled weed species, the use of a mixture of these herbicides is a factor that
minimizes the likelihood of the emergence of herbicide-resistant weed biotypes.
