Com o objetivo de avaliar diferentes aspectos da participação do nitrogênio na indução de injúrias foliares e na eficácia do herbicida glyphosate, foram desenvolvidos três experimentos, sendo dois em casa de vegetação, com as espécies Avena strigosa e Ipomoea triloba + Sorghum halepense, e um em campo, com Brachiaria decumbens. Avaliou-se a aplicação de glyphosate combinado com ureia (U), com sulfato de amônio (SA) e com U+AS, além de fertilização prévia do solo com nitrogênio e pulverização de caldas concentradas com até 20% de N. A pulverização de caldas concentradas com até 20% de N não dessecou adequadamente as espécies A. strigosa e B. decumbens, provocando danos máximos de cerca de 30%. A utilização de solução de SA ou de U+SA como veículo de pulverização do glyphosate elevou o controle de I. triloba. As soluções nitrogenadas aceleraram a atividade do glyphosate para dessecação de S. halepense, porém, sem diferenças visíveis aos 28 dias após aplicação. A escolha da dose adequada de glyphosate (1.800 g ha-1) para dessecação de B. decumbens foi fundamental para obtenção de elevado controle, sendo que a única alternativa que elevou a eficácia da menor dose do produto foi a fertilização prévia do solo com 150 kg ha-1 de SA.

O presente trabalho teve como objetivos avaliar o efeito da temperatura e da umidade na germinação e na emergência de corda-de-viola (Ipomoea triloba) e determinar o efeito de potenciais hídricos e de temperaturas na germinação de sementes e na elongação do hipocótilo e da radícula dessa espécie. Avaliaram-se os termoperíodos de 9,3 e 5 (7,5); 14,3 e 10 (12,5); 19,3 e 15 (17,5); 24,3 e 20 (22,5); 29,3 e 25 (27,5); 34,3 e 30 (32,5); 39,2 e 35 (37,5) e 44,2; 40 (42,5); e 49,2 e 45 (47,5) ºC, alternando-se durante 14 e 10 horas, e os potenciais hídricos de 0, -0,03, -0,06, -0,1, -0,2, -0,4, -0,6 e -0,9 MPa. A germinação de corda-de-viola foi descrita pela interação da temperatura e do potencial hídrico, e a taxa de elongação da radícula e do hipocótilo, em função da temperatura. Os parâmetros do modelo usado para estimar as temperaturas cardeais e o potencial hídrico base foram determinados por "probit" análise, para a germinação. Em se tratando dos processos de elongação, as temperaturas cardeais foram determinadas por regressão linear, e suas respostas à temperatura, descritas por equação de regressão de segunda ordem. Os modelos matemáticos usados descreveram os processos de germinação e elongação do hipocótilo e da radícula dessa espécie em termos de tempo hidrotérmico e temperatura, respectivamente.

ABSTRACT The control of morning glory (Ipomoea spp. and Merremia aegyptia) was evaluated in five commercial sugarcane-production fields receiving applications of the herbicides sulfentrazone (0.9 kg ha-1), amicarbazone (1.4 kg ha-1), imazapic (0.147 kg ha-1), and hexazinone + tebuthiuron (0.325 + 0.75 kg ha-1) applied pre-emergence in either the dry season (July and August) or in the semi-wet season (early October); mesotrione alone (0.192 kg ha-1) or in combination (0.12 kg ha-1) with atrazine (1.5 kg ha-1) or diuron + hexazinone (0.491 + 0.139 kg ha-1) applied post-emergence in the wet season (November), and the phytointoxication of the chemical treatments for sugarcane. Five species of morning glory (Ipomoea hederifolia, Ipomoea nil, Ipomoea quamoclit, Ipomoea triloba and Merremia aegyptia) were assessed in the experiments. The applications during the dry, semi-wet, and wet seasons resulted in similar levels of control of I. hederifolia, I. nil, I. quamoclit, and I. triloba. The herbicides imazapic and mesotrione alone resulted in lower levels of control of M. aegyptia. Imazapic and the combination of mesotrione + (diuron + hexazinone) caused greater visible phytotoxicity to sugarcane than other herbicides applied during the dry and semi-wet seasons. However, the greatest loss of production was attributed to amicarbazone.

Agricultural Production Systems

In agricultural production systems where the glyphosate-resistant soybean crop (Glycine max) is grown and the practice of crop rotation with alternative herbicides is not adopted, the exclusive and continuous use of glyphosate has led to the occurrence of resistant weed populations that may limit or compromise the benefits of this technology. Thus, the efficacy of weed management programs, including the use of residual herbicides (sulfentrazone, flumioxazin, imazethapyr, diclosulan, chlorimuron and s-metolachlor) applied in preemergence and followed by in-crop postemergence applications of glyphosate (PRE-POST) were compared to glyphosate postemergence only programs - POST. The study was conducted across nine locations during the 2009/2010 and 2010/2011 growing seasons. PRE-POST programs were efficient in the control of Amaranthus viridis, Brachiaria plantaginea, Bidens pilosa, Commelina benghalensis, Eleusine indica, Euphorbia heterophylla and Raphanus raphanistrum, with the level of control being similar when comparing the program with two applications of glyphosate POST. Some PRE-POST programs were not efficient in controlling Cenchrus echinatus, Ipomoea hederifolia and Ipomoea triloba. Sulfentrazone and diclosulam PRE-POST programs improved the control of Ipomoea triloba compared to sequential applications of glyphosate alone. No significant differences in soybean yield were observed between any of the herbicide treatments or study locations. The use of residual herbicides in preemergence followed by glyphosate in-crop postemergence provides consistent weed control and reducing early season weed competition. Furthermore, these programs utilize at least two herbicide modes of action for herbicide use diversity, which will be needed to stay ahead of resistance build-up, regardless of when weeds may appear.

ABSTRACT: This study described the epidemiological and clinical-pathological aspects of 25 outbreaks of neurological diseases in cattle caused by plants and mycotoxins in Santa Catarina state. Six of them were due to Sida carpinifolia poisoning, five to Solanum fastigiatum, five to Phalaris angusta, three to Claviceps paspali, three to Claviceps purpurea, and three outbreaks were of unknown etiology. The clinical signs observed in the affected cattle were mild to severe and characterized by generalized muscle tremors, incoordination, hypermetria, wide-based stance, intentional head tremors, dull staring eyes, and frequent ear twitching, with convulsions in some cases. At necropsy, lesions were observed only for P. angusta poisoning, characterized by gray-greenish discoloration in thalamus and midbrain. Microscopically, rarefaction and/or disappearance of Purkinje neurons with substitution by Bergmann cells were observed for S. carpinifolia and S. fastigiatum poisoning. For P. angusta poisoning, thin granular brown-yellowish pigment was observed in the cytoplasm of some neurons. Gross and microscopic findings were not observed in three outbreaks of tremorgenic disease of unknown etiology. Experiments conducted with leaves, flowers and seeds of Ipomoea indivisa and Ipomoea triloba, as well as with maize and soybean residues contaminated with Ipomoea spp. did not reproduced clinical signs.

The application of herbicide tank mixtures is a common practice in agricultural settings, especially for controlling weed communities with mono and eudicotyledons species occurring simultaneously. Therefore, thisstudy was carried out with the objective of evaluating the effectiveness and interaction of dicamba-haloxyfop tank mixtures used to control four weed species. For this, four different experiments were conducted, each with one of the plant species, namely: sourgrass (Digitaria insularis), horseweed (Conyza spp.), morning glory (Ipomoea triloba) and goosegrass (Eleusine indica). In each experiment, the experimental design consisted of completely randomized blocks, in a 4x4 factorial scheme of treatments, totaling 16 treatments with five replications, i.e., 80 plots of each species. Four doses of the herbicide dicamba (480, 240, 120 and 0 g ha-1) and four doses of the herbicide haloxyfop (60, 30, 15 and 0 g ha-1) were adopted. Percentage control was evaluated at 14 and 28 days after application (DAA) and mass of dry matter was evaluated at 28 DAA. Antagonistic, additive and synergistic effects were observed for dicamba-haloxyfop tank mixtures, with a greater preponderance of additive effects. Considering all four plant species, in different doses and dates of evaluation, 72 dicamba-haloxyfop interactions were evaluated, in which 50 were considered additives. However, the possibility of antagonism (9 interactions) or even synergy (13 interactions) cannot be ruled out, subjected to the influence of the herbicide dose, plant species and moment of evaluation.
