Fluxofenim em sementes de sorgo como protetor ao herbicida S-metolachlor
(2014-01-01)
This study aimed to evaluate the efficiency of protective fluxofenim seed treatment of sorghum hybrids DKB510 and SCG340, in order to increase the selectivity to the herbicide S-metolachlor applied pre-emergence and to ...
Selectivity of herbicides applied to Brazilian tree species at post-emergence
(Instituto Biológico, 2022-08-29)
The presence of weeds in silvicultural systems has been considered one of the main obstacles to the success of projects designed to recover degraded areas. The aim of this study was to evaluate the selectivity of herbicides ...
Herbicides selectivity on seedlings of White Leadtree (Leucaena leucocephala)Seletividade de herbicidas em mudas de Leucena (Leucaena leucocephala)
(2020-01-01)
Difficulty in controlling weeds has hindered the success of vegetation recovery projects using white leadtree (Leucaena leucocephala) seedlings in degraded areas. The use of herbicides is indispensable to mitigate damage ...
Improved herbicide selectivity in tomato by safening action of benoxacor and fenclorim
(Cambridge Univ Press, 2020-10-01)
Safeners have been widely used to reduce phytotoxicity to crops, thus serving as an alternative weed control strategy. Benoxacor and fenclorim safeners have the potential to protect plants from herbicide phytotoxicity by ...
Leaf anatomy of emerald grass submitted to quantitative application of herbicides
(2016-07-01)
The aim of this work was to evaluate the selectivity of herbicides applied in post-emergence on Zoysia japonica Steud (Poaceae) and determine associations with the leaf anatomy of this grass. The experimental design was ...
Clomazone selectivity among six cucurbit crops
(COLEGIO POSTGRADUADOS, 2005)
To determine clomazone tolerance of cucurbit crops, at different rates (0.3, 0.45, 0.6 and 0.9 kg ai ha(-1)) and to evaluate weed control efficacy of those treatments, six field studies were conducted in the 1998-1999 ...
Genetic inheritance of cytochrome P450-mediated metabolic resistance to chlorsulfuron in a multiple herbicide resistant Lolium rigidum population
(Elsevier, 2014-11)
Field evolved resistance to acetolactate synthase (ALS)-inhibiting herbicides in a multiple resistant Lolium rigidum population (VLR69) is known to be mainly due to enhanced rates of herbicide metabolism, likely involving ...
HERBICIDE SELECTIVITY IN TROPICAL ORNAMENTAL SPECIES
(Univ Federal Vicosa, 2016-10-01)
This study evaluated the selectivity of herbicides applied post-emergence on ornamental plants of Alpinia purpurata, Strelitzia reginae and Heliconia psittacorum. The study was conducted in two seasons. The experimental ...
Selectivity and residual weed control of pre-emergent herbicides in soybean crop1
(Universidade Federal de Viçosa, 2021-06-16)
The use of pre-emergent herbicides is important for the current agricultural production systems that present weeds resistant to herbicides. Considering the complexity of using these products, the objective of this work was ...
