White mold, caused by Sclerotinia sclerotiorum, is a yield-limiting disease of soybean in Brazil. Uniform fungicide trials have been conducted annually since 2009. Data from 74 cooperative field trials conducted over a 10-year period were assembled. We selected five fungicides applied two times around flowering: dimoxystrobin plus boscalid (DIMO+BOSC), carbendazim plus procymidone (CARB+PROC), fluazinam (FLUZ), fluopyram (FLUO), and procymidone (PROC). For comparison, thiophanate-methyl (TMET) applied four times was also included as a low-cost treatment. Network models were fitted to the log of white mold incidence (percentages) and log of sclerotia mass data (grams/hectare) and to the nontransformed yield data (kilograms/hectare) for each treatment, including the untreated check. Back-transformation of the meta-analytic estimates indicated that the lowest and highest mean (95% confidence interval [CI]) percent reductions in incidence and sclerotia mass were 54.2 (49.3 to 58.7) and 51.6% (43.7 to 58.3) for TMET and 83.8 (79.1 to 87.5) and 87% (81.9 to 91.6) for CARB+PROC, respectively. The overall mean (95% CI) yield responses ranged from 323 kg/ha (247.4 to 400.3) for TMET to 626 kg/ha (521.7 to 731.7) for DIMO+BOSC, but the variance was significantly reduced by a binary variable (30% threshold) describing disease incidence in the untreated check. On average, an increment of 352 kg/ha was estimated for trials where the incidence was >30% compared with the low-disease scenario. Hence, the probability of breaking even on fungicide costs for the high-disease scenario was >65% for the more effective, but more expensive fungicide (FLUZ) than TMET. For the low-disease scenario, profitability was less likely and depended more on variations in fungicide cost and soybean price.

The maize bushy stunt phytoplasma (MBS) presence in maize crop in Brazil is reported since 1971. The MBS and the corn stunt spiroplasma (CSS) are both transmitted by the Dalbulus maidis leafhopper, their only insect vector in Brazil. This leafhopper and both mollicutes survive only in maize. These pathogens are always present in maize crop, at variable levels of incidence, causing losses in grain yield. Occasionally, outbreaks have been reported. Although they are difficult to be distinguished by symptoms, both pathogens can be identified by molecular analyses. There are evidences that, in the field, the MBS incidence can be higher than the CCS incidence or vice versa. The temperature can affect MBS acquisition and transmission. The D. maidis leafhopper migrates to large distances transporting MBS. The increasing importance of MBS disease can be due to changes in the scenery of the maize crop in Brazil since the 1970s, such as more than one maize crop season. Investigation about control methods is still lacking. |
