1. Control of Italian ryegrass and Alexandergrass in corn using different corn sowing date, pre- and post-emergent herbicides
ABSTRACT Glyphosate-resistant (GR) Italian ryegrass (LOLMU) and Alexandergrass (URPLA) are troublesome weeds in corn cropping systems in Southern Brazil. The emergence pattern of those weeds is not uniform and may change according to the season’s environmental characteristics. Also, herbicide resistance has been diminishing the success of the weed control

2. Characterization of the Weed Flora in Rice Areas under Distinct Cropping Systems and Herbicide Managements
RESUMO: O objetivo deste trabalho foi avaliar a ocorrência de plantas daninhas em arroz irrigado por inundação, em função do sistema de plantio e do manejo de herbicidas na safra anterior. O experimento foi instalado em campo, em delineamento experimental de blocos casualizados dispostos em esquema fatorial 3 x 2, com oito repetições. O fator A foi o

3. Physiological quality of bean seeds after application of desiccant herbicides
RESUMO: A aplicação de herbicidas dessecantes na cultura do feijoeiro é fundamental na produção de sementes de qualidade porque antecipa a época de colheita, o que possibilita a obtenção de sementes no período de maturação fisiológica, quando se encontram com máximo acúmulo de matéria seca, elevados níveis de vigor e alta porcentagem de germ

4. Persistence of imazapyr+imazapic in irrigated rice area and effect on soybean due to soil moisture and phytoremediation in the off-season
ABSTRACT The residue of imidazolinone herbicides in soil can be detrimental to soybean cultivation in rotation with Clearfield® rice. Thus, this research aimed to evaluate the ryegrass phytoremediation capacity on the imazapyr+imazapic residue in the soil in two soil moisture conditions in the off-season, and the effect on soybean growth in the next growing

5. Halauxifen-Methyl+Diclosulam: New Option to Control Conyza spp. Prior Soybean Sowing
RESUMO: O controle de Conyza spp. antecedendo a semeadura da soja tem apresentado dificuldades no Brasil devido à presença de casos de resistência. Assim, novos herbicidas, como halauxifen-methyl + diclosulam, são importantes no manejo dessa espécie. O objetivo desta pesquisa foi avaliar a eficácia do herbicida halauxifen-methyl + diclosulam aplicado e

6. Phytotoxicity of imazapyr+imazapic on tolerant rice varieties Guri INTA CL and IRGA 424 RI
ABSTRACT Rice varieties from the Clearfield® system may present different tolerance levels to imidazolinone herbicides in function of application rate. The objective of this research was to evaluate the phytotoxicity of different rates of the formulated mixture of the herbicides imazapyr+imazapic applied on two tolerant irrigated rice varieties. The exper

7. Pre-Harvest Desiccation in Productivity and Physiological Quality of Cowpea Seeds
RESUMO: A dessecação pré-colheita é uma estratégia importante no sentido de antecipar a colheita, evitando que a semente fique no campo em condições climáticas desfavoráveis. No entanto, pouco se sabe sobre o uso de dessecantes e as épocas de aplicação destes na cultura do feijão-caupi (Vigna unguiculata). Objetivou-se neste trabalho avaliar efe

8. Fluxos de emergência, épocas de aplicação de herbicidas e sistemas de manejo de plantas daninhas em cana-de-açúcar / Emergence fluxes, herbicide application timings and weed management systems in sugarcane
The knowledge of the effects of the population dynamics and establishment velocity of weeds on the efficacy of weed management in the sugarcane crop is fundamental for the development of a rational plan of integrated weed management in the crop. Therefore, the objectives of the present research were: (i) to quantify the monthly fluxes of weed emergence year

9. Asian Rust control and performance of two soybean cultivars submitted to different fungicides and application time / Controle de ferrugem asiática e desempenho de duas cultivares de soja submetidas a diferentes fungicidas e épocas de aplicações
Phakopsora pachyrhizi Syd. &Syd. is the worst threat for soybean crop in the main producers regions around the world, where significant loses has been observed. Many variables in the quantification of damage of this disease have to be studied, such as area under the disease progress curve (AUDPC), healthy leaf area absorption (HAA), healthy leaf area duratio

10. Tebuthiuron with carbofuran in the culture of sugar cane / Tebuthiuron com Carbofuran na cultura da cana-de-açúcar
The sugarcane is one of most important cultures in Brazil, and is very important social and economically. The simultaneous use of nematicides with herbicides in sugarcane are growing every season, due to the positive along with productivities with the aim of these products. That coned responses in be explained due to high infestation of ectoparasitic nematod

11. ALTERNATIVAS DE CONTROLE QUÍMICO DO ARROZ-VERMELHO E PERSISTÊNCIA DOS HERBICIDAS (IMAZETHAPYR + MAZAPIC) E CLOMAZONE NA ÁGUA E NO SOLO / CHEMICAL RED RICE CONTROL AND PERSISTENCE OF (IMAZETHAPYR + IMAZAPIC) AND CLOMAZONE IN SOIL AND WATER
Weed infestation, mainly with red rice (Oryza spp.), is the most important factor limiting yield increase in paddy rice in Rio Grande do Sul state. Chemical red rice control is the most used tool in this area. But, its use can originate herbicide residue in water and soil that can cause carry-over to rotational crops and environmental contamination. To asses
