selective herbicide for millet

Two experiments were carried out under field conditions, in 1999/2000 and 2000/2001, at the Experimental Station of Agronomy College, at the Federal University of Rio Grande do Sul (UFRGS), Brazil, in a randomized block design with four replications, to determine the effects of living plants of sorghum genotypes with distinct capacity of production of hydrophobic root extracts, on supressing weeds. Pennisetum americanum (cultivar ADR 500) was manually sowed in area under no-till system. As new herbicides were introduced in the 1960's and 1970's many weed species that dominated before that time were now tamed, like the foxtails for an example. ha(-1)) applied at three millet growth stages (two, four and eight expanded leaves). A seletividade do tembotrione é alterada em função da. improves broadleaf weed control in proso and foxtail millets. ... millet rice and vegetables." This occurred regardless of the place evaluated, in the total area or individually in the rows or interrows, indicating lack of suppressive effect of hydrophobic exsudates under field conditions. Não se observou nenhum sinal de intoxicação das plantas de milheto pelo 2,4-D aos 15 dias após a aplicação, independentemente da dose ou época de aplicação do herbicida. The experiment was arranged in a randomized block design, in a 4 x 4 factorial scheme, with four 2,4-D rates (0. reduzir a produtividade de grãos em até 36%. (L.) Leeke) as influenced by selected herbicide, Improvement of pearl millet. ©2000-2020 ITHAKA. Ao avaliar, tembotrione no controle de plantas daninhas, constataram que o tembotrione causou menor, Para que a cultura do milheto continue se, expandindo no nosso país, é de fundamental, importância a identificação de herbicidas de, aplicação em pós-emergência, com ação sobre, essa cultura.

We reported the total number of iterations required for convergence diagnostics, and the mean square error (MSE) on posterior estimates of both random and fixed effects as well as This algorithm has also shown faster convergence rates. Posteriormente, o híbrido ADR-7010 foi submetido, no, campo, a doses crescentes de tembotrione aplicadas em dois estádios de desenvolvimento, das plantas (quatro e sete folhas completamente desenvolvidas). Tembotrione selectivity is dependent on the dose and developmental, stage of pearl millet at the time of herbicide application. Among the pre-emergent herbicides, sulfentrazone showed longer residual activity, negatively influencing the crop's yield during the time interval studied. Weed density in rows was inversely proportional to living sorghum plant population in these places. as seguintes características: pH em água: 6,1; da semeadura, realizou-se adubação de base. It was concluded that atrazine doses below 1.5 kg ha(-1) can be safely applied on growing millet, when the plants present four or more leaves at the time of application.

In the sub-plots, pearl millet hybrid ADR-7010 was sown in four periods after herbicide application, corresponding to 0, 40, 80 and 120 days after herbicide application (DAA). In 2000/2001, the treatments were the result of combinations of genotype factors and weed position ( rows or interrows). Os resultados permitiram observar que os ingredientes imazapic e imazapyr detêm maior potencial de contaminação ao ambiente, ao passo que isoxaflutole caracteriza-se pelo menor. ion (NCt) for Bayesian analysis of ordinal categorical data using mixed models. The experiment was carried out from March to June 2006, in Rio Verde, GO in soil classified as Eutroferric Red Latosol. ABSTRACT - The present study was carried out to evaluate the selectivity of the herbicide tembotrione, applied at post-emergence of pearl millet. The major symptoms of phytotoxicity, reducing the number of tillers and dry biomass were obtained from applications made in the early stages of culture and intensified with increasing dose of atrazine.

In addition, creation of a database on pearl millet production, marketing and utilisation to assist farmers and grain merchandisers, and increased extension programming on pearl millet production is needed.

Este trabalho objetivou avaliar o potencial de contaminação de herbicidas utilizados na cultura do milho. Pearl millet hybrid ADR-7010 showed high sensitivity to the residual activity of sulfentrazone, imazaquin, and diclosulam when grown immediately after herbicide application. This highly effective herbicide weed control left bare spots in our fields: good for the grower, but unfortunately an empty apartment house to wild proso millet. The test was implemented in units of 10 dm-3 of soil under conditions of a greenhouse in a completely randomized design in factorial scheme 5 x 3 with four replicates, corresponding to five dose of atrazine: 0; 0.5; 1.5; 2.5 and (4.0 kg i.a.

When trying to renovate a perennial pasture heavily infested with smutgrass, centipede, or some other unwanted grasses, it is generally advisable to spray non-selective herbicides multiple times. The bioactivity of imazaquin, diclosulam, and flumioxazin was not sufficient to affect grain yield of millet grown after soybean (120 DAA), suggesting that this interval is sufficiently long for dissipation of these herbicides. Glyphosate is a non-selective herbicide that will kill foxtail as well as most all other plants (grasses and broad leaved). and NCt algorithms overestimated the intraclass correlation when the simulated value was large (0.8). Crop rotation restrictions apply for this herbicide application, and the producer should consult the label. Utilizou-se o delineamento de blocos casualizados, em esquema fatorial 4 x 4, sendo avaliadas quatro doses de 2,4-D (0, 335, 670 e 1.005 g ha-1) aplicadas em quatro épocas [10 dias após a emergência das plantas de milheto (DAE) (3 folhas); 20 DAE (5 a 6 folhas expandidas); 30 DAE (início de emissão da inflorescência); e 40 DAE (florescimento pleno)]. 21(B) dias após a aplicação do herbicida tembotrione, em função da dose e do estádio das plantas no momento, utilização de tembotrione apresentou maior, altura das plantas foi diretamente proporcional, à dose utilizada na aplicação, embora esse, inferiores a 10%, não sendo, portanto, sufi-, ciente para prejudicar a operação de colheita, A produção de grãos das plantas de milheto, foi influenciada pela dose e época de aplicação, tembotrione, em função da dose e do estádio das plantas no, dose do herbicida tembotrione e do estádio das plantas no, avaliadas possivelmente refletiu em prejuízos, à produção de grãos.

AGROMINE 860SL 150ml/20l is a selective herbicide which kills broadleaved weeds and is applied when crop is about 30cm high. attention has been given to planting millet in the spring like other small grain crops and using selective herbicides for weed control.

Weed Science publishes original research and scholarship focused on understanding "why" phenomena occur. Selective herbicides are a type of herbicide that will only kill a certain type of plant, while leaving other plants unaffected. With respect to the mass of spike, doses below 1.5 kg ha-1 of atrazine showed greater flexibility in the application stage and can be used safely view the management of weeds in ADR-300. Crops: Rice, Maize, Millet, Sorghum, Rubber. Sencor 70 WP is a selective herbicide which effectively controls weeds in wheat, potato, soybean, tomato and sugarcane. All herbicides except the amine of 2,4-D at 0.28 kg/ha appeared to injure proso millet plants by varying degrees; however, yields were not greatly affected. Cambridge Journals publishes over 250 peer-reviewed academic journals across a wide range of subject areas, in print and online. At 15 days after application, phytotoxicity symptoms were not detected in the plants, at any rate or plant stage.

The presence of sorghum shoot residues is more important in weed supression than the presence of root residues of this crop. Todavia, as maiores doses de 2,4-D, em qualquer época de aplicação, provocaram menor acúmulo de massa verde e seca das plantas de milheto, quando se avaliaram os resultados no ponto de rolagem da cultura. herbicida tembotrione à cultura do milheto, em aplicações realizadas em dois estádios, durante o período de dezembro de 2008 a abril.
