“…Several studies have shown that some herbicides can have initial phytotoxic effects, although seedlings usually recover without severe damage, and yield loss are not observed (Díaz et al 1992;Ivany et al 2002;Thomas et al 1994;Tonks et al 1991;Volenberg et al 2002;Young et al 2003). In other studies, however, various clover species were exposed and evaluated for tolerance to different herbicides including pendimethalin and metolachlor (Tharp and Kells 2000), bentazon and 2,4-D (Evers et al 1993), 2,4-D and dicamba (Griffin et al 1984), and MCPA and 2,4-DB (Conrad and Stritzke 1980); in all cases, yield and persistence of the legume were markedly reduced.…”

(2004). Effect of five postemergence herbicides on red clover shoot and root growth in greenhouse studies. Phytoprotection, 85(3), 153-160. doi:10.7202 MCPA, 2,4-DB, flumetsulam, bentazon, haloxyfop-methyl, flumetsulam/2,4-DB and bentazon/MCPA were studied in greenhouse experiments in order to evaluate their primary effects on red clover (Trifolium pratense) growth and root injury. The influence of these herbicides on root length, plant height, crown diameter, shoot and root dry weights, shoot phytotoxicity and root injury were studied at two application rates. Variable responses in the growth parameters were observed throughout the experimental period. Herbicides did not affect root length. By the end of experiment, plant height was increased by all herbicides except MCPA and bentazon/MCPA. Crown diameter was increased only with MCPA and 2,4-DB, whereas it was not affected by the other herbicides. Bentazon reduced root dry weight while the other herbicides had no effect. In general, MCPA, bentazon, and bentazon/MCPA reduced shoot dry weight. Although all herbicides caused early foliar damage, the plants recovered by the end of experiment comparable to the control plants. Bentazon and bentazon/MCPA produced the greatest shoot damage. Roots were injured from all herbicides, yet they usually recovered over time. However, bentazon/MCPA induced more severe root injury, up to 17% of the plants, causing seedlings died. These results suggest that some herbicides used to protect red clover against weeds may also affect red clover development, increasing its vulnerability to disease. [Effet de cinq herbicides de postlevée sur la croissance de tiges et de racines du trèfle rouge lors d'essais en serre]Le MCPA, le 2,4-DB, le flumetsulam, le bentazone, le haloxyfop-méthyl, le flumetsulam/2,4-DB et le bentazone/MCPA ont été étudiés lors d'expériences en serre afin d'évaluer leurs principaux effets sur la croissance du trèfle rouge (Trifolium pratense) ainsi que sur les dommages racinaires qu'ils pourraient lui causer. Les conséquences qu'ont ces herbicides sur la longueur des racines, la taille de la plante, le diamètre du collet, les poids secs des tiges et des racines, ainsi que leur phytotoxicité pour les tiges et les dommages aux racines ont été étudiés pour deux doses d'application. Les paramètres de croissance ont eu des résultats indépendants les uns des autres tout au long de la durée des expériences. Les herbicides n'ont pas eu d'effet sur la longueur des racines. À la fin des expériences, la taille de la plante avait été augmentée par tous les herbicides sauf le MCPA et le bentazone/MCPA. Le diamètre du collet n'avait été augmenté que par le MCPA et le 2,4-DB, alors que les autres herbicides n'avaient pas eu d'effet. Le bentazone a fait diminuer le poids sec des racines alors que les autres herbicides n'ont pas eu d'ef...

“…One way to reach required forage crops quality and, at the same time, react to the change of climatic conditions is to grow new or lesser-known forage crops with different environmental requirements, such as annual ryegrass (Lolium multiflorum var. Westerwoldicum), as a feed source for cattle (Ivany et al, 2002;Orlandini et al, 2008). Annual ryegrass is a very adaptable crop.…”

Annual ryegrass (Lolium multiflorum var. westerwoldicum) is cultivated in various areas of the world as a feed for live stock. Efforts to improve the production of high-quality feed in the face of deepening climate change have increased the demand for growing non-traditional types of crops, including ryegrass. The aims of the research were to determine the spectrum of weed and fungal pathogen species and to assess dangerous species of weeds and pathogens which negatively affect forage crops of annual ryegrass grown in dry conditions. In 2018-2019 the occurrence of weeds and fungal pathogens of ryegrass was evaluated in field conditions. The assessed lands were located in dry climatic conditions of South Moravia (Czech Republic). The vegetation recording was done on phytosociological plots of 12 m 2 . A total of 57 weed species were identified in the plots, where 12 species were toxic and 16 species were undesirable. The most problematic weeds and poisonous species were: Aethusa cynapium, Datura stramonium, Equisetum palustre, Euphorbia helioscopia, Fumaria officinalis and Solanum nigrum, which can cause health problems if present in cattle feed. A pathogenic infection caused by Blumeria graminis, Puccinia graminis var. graminicola and P. coronata var. coronata, Gaeumannomyces graminis and Drechslera sp. was identified on the ryegrass plants in the experimental plots during the vegetation. Blumeria graminis was the most abundant, but it did not endanger the final feed. The data was processed by CCA analysis.
