In the organic system, one of the biggest obstacles faced by the farmer is the management and control of weeds. In this context, the use of heat treatment with fire may be seen as an interesting alternative, because of its characteristic of not leaving chemical
residues in the soil and water. The objective was to evaluate the effect of the time of application of the flamethrower in weed control as compared to manual control and mechanical methods. The experiment was arranged in a randomized block design with four replications and seven treatments, totaling 28 plots with dimensions of 1.0 x 1.0 m. The treatments consisted of five application times for the flamethrower (0, 5, 10, 15 and 20 s m-2) and two types of weeding (manual and mechanical). Infestation percentage, fresh and dry weight assessments of the remaining weeds in each plot were made. The application of 10 s m-2 for the flamethrower was efficient in controlling weeds in early stage of development and it can be used as an alternative to mechanical and manual weeding, in weed control.
No sistema orgânico, um dos maiores entraves enfrentados pelo agricultor é o manejo e controle de espécies daninhas. Nesse contexto, o uso do tratamento térmico com fogo pode ser visto como uma alternativa interessante, dada sua característica de não deixar resíduos químicos no solo e na água. O objetivo deste trabalho foi avaliar o efeito do tempo de aplicação do lança-chamas no controle de plantas daninhas, em comparação aos métodos de controle manual e mecânico. O experimento foi disposto em delineamento de blocos casualizados, com quatro repetições e sete tratamentos, totalizando 28 parcelas experimentais com dimensões de 1,0 x 1,0 m. Os tratamentos foram constituídos por cinco tempos de aplicação do lança-chamas (0, 5, 10, 15 e 20 s m-2) e dois tipos de capina (manual e mecânica). Foram feitas avaliações de porcentagem de infestação e da massa da matéria fresca e seca das plantas daninhas remanescentes em cada parcela. A aplicação de 10 s m-2 de lança-chamas mostrou-se eficiente em controlar as plantas daninhas em estádio inicial de desenvolvimento, podendo ser utilizada como alternativa às capinas mecânicas e manual no controle das plantas daninhas.

Fusariosis, caused by the fungus Fusarium subglutinans f. sp. ananas (Syn. F. guttiforme), is one of the main phytosanitary threats to pineapple (Ananas comosus var. comosus). Identification of plant cell responses to pathogens is important in understanding the plant?pathogen relationship and establishing strategies to improve and select resistant cultivars. Studies of the structural properties and phenolic content of cell walls in resistant (Vitoria) and susceptible (Perola) pineapple cultivars, related to resistance to the fungus, were performed. The non-chlorophyll base of physiologically mature leaves was inoculated with a conidia suspension. Analyses were performed post-inoculation by light, atomic force, scanning and transmission electron microscopy, and measurement of cell wall-bound phenolic compounds. Non-inoculated leaves were used as controls to define the constitutive tissue characteristics. Analyses indicated that morphological differences, such as cell wall thickness, cicatrization process and lignification, were related to resistance to the pathogen. Atomic force microscopy indicated a considerable difference in the mechanical properties of the resistant and susceptible cultivars, with more structural integrity, associated with higher levels of cell wall-bound phenolics, found in the resistant cultivar. p-Coumaric and ferulic acids were shown to be the major phenolics bound to the cell walls and were found in higher amounts in the resistant cultivar. Leaves of the resistant cultivar had reduced fungal penetration and a faster and more effective cicatrization response compared to the susceptible cultivar.
