“…However, the study revealed that interaction of inhibitors of hydroxyphenyl pyruvate dioxygenase and ALS was antagonistic (Schuster et al, 2008). Since this antagonism is not catastrophic and may be overcame by increasing the rate of application of ALS-inhibitors (Duus et al, 2018), use of mixtures of inhibitors of ALS and hydroxyphenyl pyruvate dioxygenase is possible. In particular, in Ukraine, Synhenta Company utilized registered preparation Eliumis, the active substances of which are ALS-inhibiting nicosulfuron and ALS-inhibiting mesotrione.…”

“…Therefore, the resistance to this class of herbicides has not yet become as widespread as resistance to ALS-inhibitors (Heap, 2021). The analysis of studies of interaction of inhibitors of hydroxyphenyl pyruvate dioxygenase with herbicides of other classes may lead to a conclusion that their best partners at the moment are ALSinhibitors (Duus et al, 2018) and herbicides that inhibit electron transport in the photosystem of 2 chloroplasts (PS II) (Armel et al, 2005;Walsh et al, 2012). Especially promising for developing such mixtures may be a new herbicide of the class of inhibitors of hydroxyphenyl pyruvate dioxygenase -tolpyralate (Kikugawa et al, 2015;Tonks et al, 2015;Metzger et al, 2018).…”

Many countries are now facing the problem of increase in resistant biotypes of weeds. The spread of herbicide-resistant weeds across agrophytocenoses poses a threat of decrease in the effectiveness of use of herbicides in agricultural fields. In order to develop anti-resistant compositions of herbicides for protection of maize (Zea mays L.) crops, we studied effects of interaction and efficiency of weed control in greenhouse and field experiments. We studied the possibility of combined use of 4-hydroxyphenyl pyruvate dioxygenase-inhibiting herbicide tolpyralate and inhibitor of transport of electrons in photosystem 2 of chloroplasts – terbuthylazine – and acetolactate synthase-inhibiting rimsulfuron. In greenhouse experiments on model objects, we found that interaction in the mixtures of tolpyralate with rimsulfuron was antagonistic, but the antagonism may be overcome by increasing the rate of applied rimsulfuron. At joint use of tolpyralate and terbuthylazine, a synergistic increase in phytotoxic effect was observed, caused by increase in the effectiveness of the blocking electron-transport chain and increase in intensity of formation of reactive oxygen species. According to the results of the field experiments, we drew the conclusion that the efficacy of using the mixture of tolpyralate and rimsulfuron depends on the species composition of weeds. In the presence of rimsulfuron-resistant weeds, interaction with tolpyralate becomes antagonistic even in the conditions of increased rate of application of rimsulfuron, and thus the effectiveness of the protection significantly decreases. At the same time, after applying tank mixture of tolpyralate with terbuthylazine, the synergistic character of the interaction was maintained toward a broad range of species of grass and dicotyledonous weeds, providing high efficiency of maize crop protection. The herbicide compositions that were analyzed and are presented in the article allow one to decrease the possibility of emergence of resistant biotypes of weeds, and also to effectively control the already existing resistant biotypes.

“…This issue may be related to a reduction in detoxification ability compared with the younger plants, as well as their thinner cuticle, which probably allows to retain, absorb, and translocate the greater amounts of the utilized herbicides. In the research of [59], the antagonism effect was observed when 28.5% nicosulfuron mixed mesotrione by ADM model on canola at 10, 17, and 40 days after treatment. An increased level of Reactive Oxygen Species (ROS), produced by the mesotrione, may block the inhibitory effect of nicosulfuron on ALS [55].…”

Frequent and intensive use of similar modes of action herbicides increases selection pressure resulting in nature adapt and a number of herbicide-resistant weeds. The most effective methods to prevent and delay herbicide-resistant weeds are herbicide tank mixture and adjuvant mixed herbicides. This chapter intends to explain the advantages of herbicide tank mixture and adjuvant mixed herbicides. In addition, the models of estimated herbicide mixture interaction response have been explained. Although herbicide mixtures have benefits, they may present risks leading to soil pollution and affecting soil fauna such as earthworms. Therefore, we discussed the negative effect of mixture herbicides on Eisenia fetida. On the other hand, various models to calculate mixture herbicide toxicity on earthworms will be present in this chapter.

“…Logarithmic spraying is well suited to study the joint action of herbicide mixtures and the effect of adjuvant on herbicide potency. 17 By including many herbicide products in a test, the various locations can be considered genuine replications and one can get an impression of the variation of the potency and selectivity of the product leads. 8 Systematic use of a log-sprayer and development of procedures to ensure precise spraying and thus precise ED x parameters (e.g.…”

BACKGROUND In field experiments, assessment of herbicide selectivity and efficacy rarely takes advantage of dose–response regressions. The objective is to demonstrate that logarithmic sprayers, which automatically make a logarithmic dilution of a herbicide rate, can extract biologically relevant parameters describing the efficacy of herbicides in crops, and compare localities and time of assessment. RESULTS In a conventional and an organic field, canola, white mustard, and no crop plots were sprayed with diflufenican and beflubutamid. A mixed effect log‐logistic dose–response regression, with autoregressive correlation structure, estimated ED50 and ED90 for visual and Excess Green Index symptoms at various days after treatment (DAT). For visual assessment, ED50 differed within no crop between locations for beflubutamid at 12 DAT and 26 DAT. For diflufenican, the ED50 was different within crops at the two fields at 12 DAT, but not at 26 DAT. The Excess Green Indices at ED50 were not different among herbicides, locations, and corps; ED90 differed for white mustard and canola for beflubutamid but not for diflufenican. CONCLUSION Suitable nonlinear regression models are now available for fitting dose–response data from a logarithmic sprayer in field experiments. The derived parameters (e.g. ED50) can compare selectivity and efficacy at numerous cropping systems. © 2018 Society of Chemical Industry
