ABSTRACT.
The chemical control of Fusarium Head Blight (FHB) using fungicide has remained an unresolved challenge worldwide. Experiments using fungicides to control the disease have shown large difference of effi ciency due to multiple factors (fungicides, moment and method of application, nozzle types, and weather conditions at the time of application, etc.) responsible for disease development. Besides adequate disease control, the fungicides are also expected to act on toxin production. Results have shown that highly susceptible cultivars cannot be fully protected under severe epidemic conditions. For this reason these cultivars need to be withdrawn from commercial production and chemical control be applied as
preventive measure based on the FHB developmental models and weather forecasts. Presently one of the most effi cient fungicides to control FHB in the Southern Cone region is Metconazole followed by the Tebuconazole. Other fungicides (Prochloraz, Thiabendazole, Carbendazim, etc.) used earlier are less effi cient compared to the triazoles mentioned earlier. Under experimental conditions, nozzle types like Twinjet 60 or Turbo TeeJet Duo have shown an increase the disease control effi cacy. The earliest time to spray is after complete heading, beginning of fl owering or mid fl owering depending on the year and weather conditions.

ABSTRACT: In semiarid agricultural systems, irrigation may increase soil organic matter (SOM) due to higher biomass
production. However, aboveground production tends to increase more than belowground biomass, and in no-till
systems SOM responses to irrigation would strongly depend on the fate of crop residues left on the soil surface.
Litter decomposition and SOM formation can also be affected by irrigation due to changes in water dynamics, but
little is known about the impacts of irrigation on the pathways of SOM formation. We used dual 13C and 15N
labeled maize litter to quantify the effect of irrigation on the contribution of aboveground crop residues to SOM
formation in semiarid, no-till agricultural systems. We incubated the litter in a continuous maize cropping system
with two treatments, dryland and irrigated, and measured litter decomposition and its contribution to different
SOM pools. Irrigation had a larger effect on litter C and N losses than on the formation of new SOM. After 13
months the C and N losses from the litter layer were 24% higher under irrigation, but there were no treatment
differences in the litter-derived C and N recovered in SOM. Most of the litter-derived organic matter (OM) was
found in the mineral associated OM pool (MAOM), but irrigation did not affect the amount of litter-derived OM
found as MAOM or as particulate organic matter. Irrigation increased the amount of litter-derived OM found in
macroaggregates, and this observation was more related to a higher aggregation than to aggregate enrichment in
the irrigated treatment. Our results suggest that a smaller proportion of aboveground crop residues will form
SOM in irrigated systems compared to dryland conditions and may help to partially explain why irrigation has a
stronger relative effect on crop productivity and C inputs than on SOC stocks in semiarid agricultural systems. MenosABSTRACT: In semiarid agricultural systems, irrigation may increase soil organic matter (SOM) due to higher biomass
