ABSTRACT - In this paper, we describe poisoning outbreaks of Xanthium strumarium in cattle on the borders of the Araguari River, Southeastern Brazil. In this region, several hydroelectric plants promote transient flooding, which creates a favorable environment for the invasion of X. strumarium in extensive areas, often as the predominant species in those areas. The outbreaks occurred between July and September (dry season). Bovines of all ages were affected, including suckling animals. Mortality varied from 2% to 5.5%. The animals exhibited ataxia, weakness, loss of balance, recumbency, and the majority were found dead. Laboratory results showed a marked increase in the serum activities of alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and gamma-glutamyltransferase. Histological and ultrastructural changes in the liver consisted of centrilobular necrosis and hemorrhage. On toxicological evaluation, the dicotyledons contained 0.30 μg/mg of atractyloside and 0.37 μg/mg of carboxyatractyloside. Considerable economic loss has occurred in this region due to the lack of knowledge regarding X. strumarium as a toxic plant and its adaptation to the environmental and climatic conditions of the region, which have made the condition endemic.

ABSTRACT.
Postharvest diseases control in Citrus is essential to maintain fruit quality during storage, overseas transport and selling. Green mold caused by Penicillium digitatum is one of the most important postharvest diseases. In Uruguay it has been controlled by synthetic fungicides. Fungicide resistant strains make it neccesary to develop new strategies to control postharvest decay in Citrus. In view of this situation, we attempted to develop an effective alternative management to control Penicillium digitatum imazalil (IMZ) resistant strains. For this purpose 'Valencia' oranges were inoculated with imazalil sensitive SS-22 and resistant RS-20 strains selected previously according to their aggressiveness on lemon fruits. From 18-22 hours before treatments, each fruit was inoculated by wounding (depth 2 mm, breadth 1 mm) and inoculating with a P. digitatum spore suspension (1,0 × 106 spores/ml). Incidence and sporulation was evaluated after 7, 11 and 15 days at 20°C. Similarly, an experimental packing-line was used to evaluate chemical alternatives and application methods. Imazalil with pyrimethanil (Philabuster"-PI, 750 ppm) mixture or combined with potassium sorbate (KS, 2%) resulted in a significant control of the incidence and sporulation of the most aggressive P. digitatum resistant strain. The incidence was reduced from 75-80% in controls to 0-8% in treatments. IMZ applied at 1500 ppm did not control the incidence or sporulation of the resistant strain. The application of KS reduced strains incidence and sporulation by 50-70%. No difference (p?0.05) was found in the pathogen control comparing both application methods. All treatments were effective on reducing sensible strain sporulation, being only PI alone or combined with KS, effective for the resistant strain. We concluded that PI (750 ppm) alone or with KS at 2% can be applied as an alternative management to control Uruguayan Penicillium digitatum sensitive and resistant IMZ strains. MenosABSTRACT.
