13. Quitosana associada com extratos vegetais no controle pós-colheita de antracnose em mamão ‘formosa’
RESUMO O uso excessivo de produtos químicos na cultura do mamão (Carica papaya) coloca em risco a eficácia de fungicidas, em razão dos problemas de resistência dos patógenos a esses produtos, além da possibilidade de resíduos tóxicos colocarem em risco a saúde humana e o ambiente. Diante disto, o presente trabalho teve por objetivo avaliar a eficá

15. Antagonism between fungicide-insecticide treatments and dietholate in irrigated rice seeds
Resumo: Para proporcionar maior seletividade do herbicida clomazone à cultura do arroz, pode-se utilizar o protetor dietholate em conjunto com outros tratamentos de sementes (ST), o que possibilita o uso de doses maiores do herbicida. O objetivo do trabalho foi avaliar a interação entre o tratamento de sementes que utilizam fungicidas e inseticidas e o pr

16. Cytogenotoxicity of rice crop water after application of the tricyclazole fungicide
ABSTRACT Tricyclazole is currently one of the fungicides recommended for the treatment of diseases in irrigated rice. However, there is relatively little information on its cytotoxic and genotoxic potential. The objective of this study was to evaluate the cytotoxicity and genotoxicity of rice crop water after apllication of the tricyclazole fungicide through

17. AERIAL AND GROUND APPLICATION OF FUNGICIDE IN CORN SECOND CROP ON DISEASES CONTROL
ABSTRACT The aim was to evaluate the diseases severity on corn second crop. The research was conducted on the agricultural year of 2013 and 2014, evaluating the application quality over the fungicide spraying. The hybrid used was PIONEER 30k75 BT HERCULEX, evaluating the diseases severity previously and after the fungicide spraying, spray deposition on the c

18. Is the emergence of fungal resistance to medical triazoles related to their use in the agroecosystems? A mini review
Abstract Triazole fungicides are used broadly for the control of infectious diseases of both humans and plants. The surge in resistance to triazoles among pathogenic populations is an emergent issue both in agriculture and medicine. The non-rational use of fungicides with site-specific modes of action, such as the triazoles, may increase the risk of antifung

19. Management of blight of bell pepper (Capsicum annuum var. grossum) caused by Drechslera bicolor
Abstract Sweet or bell pepper is a member of the Solanaceae family and is regarded as one of the most popular and nutritious vegetable. Blight, in the form of leaf and fruit blight, has been observed to infect bell pepper crops cultivated at the horticulture farm in Rajasthan College of Agriculture, Udaipur, India. Based on disease severity, we attempted to

20. ENRAIZAMIENTO DE VITROPLANTAS DE MEMBRILLO (Cydonia oblonga) POR MEDIO DE INMERSIÓN TEMPORAL AUTOMATIZADA Y SU ACLIMATACIÓN
ABSTRACT Quince (Cydonia oblonga) is a non-traditional fruit tree found in Costa Rica that has therapeutic and nutritional properties; however its slow growth and root formation prevents the production of a homogeneous population when using conventional farming techniques. Hence, the aim of this research project was to generate uniform plant material in a re

21. Effect of fungicide on Fusarium verticillioidesmycelial morphology and fumonisin B1 production
The effect of fludioxonil + metalaxyl-M on the mycelial morphology, sporulation and fumonisin B1 production by Fusarium verticillioides 103 F was evaluated. Scanning electron microscopy analysis showed that the fungicide caused inhibition of hyphal growth and defects on hyphae morphology such as cell wall disruption, withered hyphae, and excessive septation.

22. Biological control of Fusarium oxysporum f. sp. phaseoli by Trichoderma harzianum and its use for common bean seed treatment
Biological control of seed-borne pathogens has shown to enhance germination and physiological quality of seeds. The objectives of this study were to evaluate the in vitro antagonistic effect of five Trichoderma harzianum isolates (CEN287, CEN288, CEN289, CEN290, and CEN316) against Fusarium oxysporum f. sp. phaseoli (Foxy) and test its potential use in seed

23. Silicon improves the emergence and sanity of rice seedlings obtained from seeds infected with Bipolaris oryzae
This study investigated the importance of silicon (Si) in rice grain husk in association with fungicide treatment for preventing Bipolaris oryzae transmission from seed to seedling and the improvement in seedling emergence. Plants from cv. Oochikara and its mutant (lsi1 mutant) defective in active Si uptake were grown in nutrient solution without (-Si) or wi

24. Effect of foliar application of potassium silicate on the progress of coffee leaf rust
In order to evaluate the effect of potassium silicate spray on the control of coffee leaf rust and coffee yield, an experiment was conducted during the 2005/2006 and 2006/2007 growing seasons on Coffea arabica cv. Catuaí Vermelho IAC 144, in a location situated at an elevation of 850 m in Coimbra, Minas Gerais, Brazil. The treatments consisted of: 1 - potas
