37. Production and Optimization of Killer Toxin in Debaryomyces hansenii Strains
ABSTRACT Postharvest diseases of fruits and vegetables result in critical losses of production in worldwide. The losses often are caused by fungi and nowadays, most fungal pathogens are controlled by several strategies such as the use of fungicides. However, most of the fungicides are chemical-based compounds and are dangerous to human health and the nature.

38. 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

39. Conyza canadensis: Green Extraction Method of Bioactive Compounds and Evaluation of Their Antifungal Activity
Synthetic fungicides are a common treatment for post-harvest diseases in fruits, although demand is increasing for alternatives such as biopesticides. The aim of this work was to investigate the presence of naturally occurring antifungal compounds in Brazilian specimens of the weed Conyza canadensis. Two compounds [(4Z)-lachnophyllum lactone and (4Z,8Z)-matr

40. Richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides in rice paddy fields
ABSTRACT The objective of this study was to verify the richness and density of aquatic benthic macroinvertebrates after exposure to fungicides and insecticides of the rice paddy fields. In the crop seasons of 2012/13 and 2013/14, field experiments were performed, which consisted of single-dose applications of the fungicides trifloxystrobin + tebuconazole and

41. Determinação de agrotóxicos na água e sedimentos por HPLC-HRMS e sua relação com o uso e ocupação do solo
In present times, the Brazil is in the middle of the largest pesticide consumers worldwide, which demands proper control of environmental contamination. This study evaluated herbicides, acaricide, insecticides and fungicides in water and sediment carried-out from Lageado Tacongava hydrographic basin, Rio Grande do Sul, Brazil. For analysis, a QuEChERS (Quick

42. Potential effects of fungicide and algaecide extracts of Annona glabra L. (Annonaceae) on the microalgae Raphidocelis subcapitata and on the oomycete Pythium
ABSTRACT Annona glabra L. is a semi-deciduous tree that contains several active substances, including secondary metabolites, with antifungal activity. Phytopathogenic strains of the genus Pythium cause billion dollar losses all over the world on natural and crop species. Searching for eco-friendly algaecides and fungicides, we analyzed the effects of acetone

43. 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

44. ADJUVANTS IN FUNGICIDE SPRAYING IN WHEAT AND SOYBEAN CROPS
ABSTRACT The objective of this study was to determine whether the combination of adjuvants to fungicides significantly alters the spray physicochemical characteristics, and potentiates the chemical control of foliar diseases, in that it may affect yield components in wheat (Triticum aestivum) and soybean (Glycine max). The experimental design was completely

45. 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

46. Impact of Fungicide Residues on Polymerase Chain Reaction and on Yeast Metabolism
ABSTRACT The indiscriminate use of pesticides on grape crops is harmful for consumers´ healthin “in natura” consumption and in the ingestion of wine and grape juice. During winemaking, a rapid and efficient fermentation stage is critical to avoid proliferation of contaminating microorganisms and to guarantee the product´s quality. Polymerase chain reac

47. Effects of Different Numbers of Fungicide Application on the Proximate Composition of Soybean
This study aimed to evaluate the effect of strobilurin (pyraclostrobin) + triazole (epoxiconazole) fungicides application on the proximate composition of soybeans. Six treatments of varying numbers of fungicide applications following soybean germination, termed T1 (control), T2, T3, T4, T5, and T6, were assessed for this experiment. Based on the results, the

48. Methyl Salicylate: an Alternative Extraction Solvent for Dispersive-Liquid-Liquid Microextraction of Benzimidazole Fungicides in Water Samples Followed by High‑Performance Liquid Chromatographic Analysis
Methyl salicylate based dispersive liquid-liquid microextraction method of benzimidazole fungicides (i.e., carbendazim, thiabendazole and fluberidazole) in water samples and analysis by high performance liquid chromatography has been firstly developed. The target fungicides in aqueous sample were extracted under the selected conditions of 250 µL of methyl s
