“…Moreover, the compact crop canopy might have curbed weed growth and finally less biomass. These verdicts are in line with Gohil et al [9], Harpreet et al [22], Patel et al [23] and Kutariye et al [24].…”

The farmers of Gujarat have turned to soybean cultivation as soybean demand is increasing promisingly. Improper weed management is one of the reasons for the large yield gap between the potential and the actual yield of soybean harvested by the farmers. So, the selection of different herbicides in soybean is necessary for effective management of complex weed flora. An experiment was plotted with an aim of enhancing summer soybean yield through evaluation of herbicidal weed management options on medium black calcareous soil at Junagadh Agricultural University, Junagadh during summer season of 2021. The experiment comprised 12 treatments that were arranged in randomized block design with 3 replications. The outcomes of the results revealed that following to weed-free treatment, pre-mix pendimethalin + imazethapyr 750+50 g/ha as pre-emergence (PE) fb hand-weeding (HW) & inter-culturing (IC) at 30 days after sowing (DAS), HW at 15 DAS fb pre-mix propaquizafop + imazethapyr 50+75 g/ha as post-emergence (PoE) at 30 DAS, HW at 15 DAS fb pre-mix fluazifop-p-butyl + fomesafen 125+125 g/ha (PoE) at 30 DAS and pre-mix pendimethalin + imazethapyr 750+50 g/ha (PE) fb pre-mix fluazifop-p-butyl + fomesafen 125+125 g/ha (PoE) at 30 DAS enhanced growth parameters viz., plant height, branches per plant; yield attributes i.e., number of pods per plant and ultimately lead to greater seed yield and stover yield. These herbicidal weed management options also reduced population in addition to dry matter of weeds and had less reduction in yield due to better control of weeds, less crop-weed competition and higher weed control efficiency.

“…The application of oxyfluorfen and flumioxazin at pre-emergence, and linuron and diuron at post-emergence were also selective to the cultivar Chonan. Mohite et al (2015) and Patel et al (2020) evaluated the effect of herbicides on garlic bulb production and found that pendimethalin applied at pre-emergence resulted in higher yield than oxyfluorfen. Kumar et al (2013) also found higher garlic bulb yield Guerra et al (2022) Application timing affects the selectivity...…”

A modalidade de aplicação afeta a seletividade de herbicidas para a cultura do alho

O principal método de controle de plantas daninhas na cultura do alho é o químico, contudo essa cultura é extremamente sensível à herbicidas, podendo sofrer injúrias e redução de produtividade dependendo dos produtos utilizados, modalidade de aplicação, dose, cultivar, dentre outros. Assim o objetivo do presente estudo foi avaliar a seletividade de herbicidas para a cultura do alho cultivar Chonan, aplicados em diferentes modalidades de aplicação. Para isso foi conduzido, em casa de vegetação, um experimento em delineamento inteiramente casualizado, com quatro repetições. O experimento contou com 16 tratamentos, dispostos em esquema fatorial 8 x 2. O primeiro fator é representado por uma testemunha sem herbicida e sete herbicidas (linuron, diuron, pendimethalin, s-metolachlor, oxyfluorfen, flumioxazin e oxydiazon), e o segundo fator pela modalidade de aplicação (pré-emergência ou pós emergência). Foi avaliado a fitointoxicação, taxa fotossintética, morfometria de estômatos, diâmetro de bulbos e produtividade da cultura do alho. As aplicações em pré-emergência foram mais seletivas em comparação com as de pós emergência. Os herbicidas linuron, diuron, s-metolachlor e oxadiazon aplicados na pré emergência e s-metolachlor, oxyfluorfen, flumioxazin e oxadiazon em pós-emergência não foram seletivos para o alho, cultivar Chonan. O pendimethalin foi o herbicida que apresentou a maior seletividade, independentemente da época de aplicação. Enquanto que oxyfluorfen e flumioxazin foram seletivos quando aplicados em pré-emergência e linuron e diuron em pós emergência do alho cultivar Chonan.
