“…When temperatures were higher than 12°C, the efficacy was sufficient even when the rainfall before application was low. The ALS enzyme activity in weeds increases with increasing temperature (De Queiroz et al, 2013). Also, in study of Trezzi et al (2021), absorption and translocation of imazamox in Euphorbia heterophylla L. decreased when the application was followed by a low temperature regime (10/5°C) compared to regimes with higher temperatures (20/15 and 30/25).…”

Effect of weather conditions on efficacy of different herbicides used in Bromus sterilis control

2023

Efficacy of herbicides is strongly affected by weather conditions shortly before and after application. Small‐plot field trials were carried out in winter wheat in north‐west Bohemia, Czech Republic, Central Europe from 2011 to 2018. The relationship between meteorological characteristics and efficacy of acetolactate synthase inhibiting herbicides (mesosulfuron + iodosulfuron, propoxycarbazone and pyroxsulam) on Bromus sterilis was studied. The effects of precipitation before and after herbicide application, mean temperature and sunshine hours after the application were found to be statistically significant. The total precipitation 30 days before herbicide application had the greatest effect on herbicide efficacy. Mean efficacy significantly increased with increasing precipitation, when mean temperatures 5 days after treatment were above 9°C. The herbicide mesosulfuron + iodosulfuron was most affected by amount of precipitation while efficacy of pyroxsulam was minimally affected. When total rainfall amounted to 30 mm in the 20–40 days after herbicide application, there was no significant effect of total rainfall before herbicide application. In order to prepare the best weed control strategy against B. sterilis, weather conditions before and after the application term should be considered so that the growers can adjust for proper application timing and be prepared for a second application with a suitable herbicide.

“…The herbicides inhibitors of the acetolactate synthase enzyme (ALS) have several benefits to agriculture, including broad-spectrum of weed control, low toxicity to mammals and efficacy at low doses (Powles and Yu, 2010;Queiroz et al, 2013). The iodosulfuron-methyl herbicide is an ALS inhibitor that is registered for the control of mono and dicotyledonous species in several cereal crops, including wheat, rye and barley (Brigante et al, 2005).…”

An Innovative Method to Evaluate the Impact of Temperature on Iodosulfuron-Methyl Selectivity to Oat Crop

et al. 2017

-Temperature affects the selectivity of post-emergence herbicides in a complex manner. The objective of this work was to develop a method to estimate the impact of temperature on herbicide selectivity using the white oat (Avena sativa) crop and iodosulfuron-methyl as study models. Greenhouse/growth-chamber experiments were conducted using a completely randomized design with the treatments arranged as a bi-factorial, with three repetitions. The first factor consisted of six temperatures (10, 15, 20, 24, 28 and ). For each temperature, regression curves were fitted to the dose-response data. The rate of herbicide efficacy was computed through the method first proposed in this study. The crop tolerance to the herbicide increased proportionally to the temperature, suggesting the product detoxification is improving crop selectivity. In practical terms, it is predicted that white oat crop tolerance to iodosulfuron-methyl increases in regions of the world with high temperatures. The method developed here also can be used to understand the effect of temperature on herbicide efficacy on weeds.Keywords: Avena sativa, crop tolerance, environmental factors, herbicide detoxification.

O objetivo deste trabalho foi desenvolver um método para estimar o impacto da temperatura na seletividade de herbicida, utilizando aveia cultivada (Avena sativa) e iodosulfuron-methyl como modelos de estudo. Os experimentos foram conduzidos em casa de vegetação/câmaras de crescimento, utilizando-se delineamento inteiramente casualizado, com os tratamentos arranjados como bifatorial, com três repetições.
