The use of adjuvants is an effective way to improve weed control. We evaluated the effect of a non-ionic surfactant (NIS, Contact) and a crop oil concentrate (COC, Renol) on the efficacy and rainfastness of the rimsulfuron on redroot pigweed (Amaranthus retroflexus L.) and common lambsquarters (Chenopodium album L.) in pot studies as well as NIS surfactant in a potato under field conditions. In outdoor pot studies, NIS (0.15 L ha− 1) and COC (0.5 L ha− 1) did not improve the efficacy of rimsulfuron on A. retroflexus while they enhanced the performance and rainfastness of rimsulfuron 14 and two-fold on Chenopodium album at those rates, respectively. However, increasing the NIS concentration to 1 L ha− 1 increased rimsulfuron efficacy by 11-fold for A. retroflexus compared to around 3-fold for C. album. The same treatment also reduced the rainfastness of rimsulfuron on A. retroflexus while improving the rainfastness of rimsulfuron on Chenopodium album compared to 0.04 L ha− 1. The ED50 and ED90 values indicated that the addition of the 0.2 L ha− 1 of NIS improved the efficacy of both recommended (60 g ai. ha− 1) and the reduced (30 g ai. ha− 1) doses of rimsulfuron in field conditions. The highest potato yield (60 t ha− 1) was recorded when rimsulfuron was applied at recommended dose at three different crop growth stages including the development of leaves (S1), harvestable vegetative plants (S4), and tubers (S7), without using a NIS. Overall, the NIS improved rimsulfuron efficacy, especially when the herbicide was applied at a lower dose.

Frequent use of herbicides may impose a risk on non-target species. The objective was to test the combined toxic effect of binary herbicide mixtures—metribuzin:halosulfuron and metribuzin:flumioxazin—on non-target earthworms in two test systems: filter paper and a soil toxicity test system. The joint action experiments were independently run twice to substantiate the findings. The most potent individual herbicide was metribuzin, with a 50% lethal concentration (LC50) of 17.17 µg ai. cm−2 at 48 h in the filter paper test. The toxicity of the individual herbicides on the filter paper test was ranked as metribuzin>halosulfuron>flumioxazin. In the soil test, metribuzin and halosulfuron had high toxicity with an LC50 of 8.48 and 10.08 mg ai. kg−1, respectively, on day 14. Thus, the individual herbicide ranking did not change between the filter paper and artificial soil tests. The herbicide’s mixed effect in both test systems showed a consistent antagonistic effect relative to a Concentration Addition reference model. It indicates that the mixtures retracted the herbicide’s action in the earthworms.

“…Metribuzin is a common selective herbicides in potato which is controlling vast range of species including broad and narrow leaves [10] except for Solanum sarrachoides (L.) [11]. Intensive use of metribuzin caused increasing number of resistant weeds [12,13]. The most important resistant weed species are Solanum.…”

“…It inhibits acetolactate synthase (ALS), an important enzyme in the biosynthesis of branched-chain amino acids (leucine, isoleucine and valine) in plants [19]. Pre and Post emergence application of rimsulforun effectively controlled C. album and A. retroflexus that are important weeds in the crop [8,20,21]. The optimization of herbicide use allows for dose reductions [12].…”

Using adjuvants to optimize and increase the efficacy of herbicides is an acceptable manner to reduce herbicides undesirable impact on the environment in sustainable agriculture. In this study, it was demonstrated that the application of 0.1% of the non-ionic surfactant (NIS, Contact) and 0.5 L ha-1 of a crop oil concentrate (COC, Renol) did not improve the efficacy of rimsulfuron on Amaranthus retroflexus. In contrast, the same treatments enhanced performance and rainfastnes of rimsulfuron in Chenopodium album in pot expriments. Increasing non-ionic surfactant concentration to 1 L ha-1 increased rimsulfuron performance around 11-fold for Amaranthus retroflexus compared to around 3-fold for Chenopodium album. The same treatment, also reduced the rainfastness of rimsulfuron on Amaranthus retroflexus while improving the rainfastness of rimsulfuron on Chenopodium album. Measured ED50 and ED90 values of rimsulfuron indicated that the addition of the 0.2 L ha-1 of NIS improved the recommended (60 g ai. ha-1) and the reduced (30 g ai. ha-1) of rimsulfurom in field. The highest potato yield measured (60 tons per ha) when 60 g ai. ha-1 rimsulfuron was applied at three stages (S1, S4, and S7) without using a NIS; not significant differences were measured when the same dose of rimsulfuron was applied at the three (S1, S4, and S7) and two (S1, S4) stages with NIS.
