Circles for Rice | Brazil Update by Kelly Downing

Sáo Borja
Sáo Paolo
I was able to visit several fields in Brazil during a visit November 8 - 15. We really covered a lot of country. Once again, I was struck by the wonderful people, as well as by the great beauty and agricultural potential of Brazil. It was a great pleasure to be hosted by Embrapa Professor Jose Parfitt during part of the trip.

Pelotas and Bage areas:
Embrapa: Unusually cool, wet spring, so delayed emergence (planted September, just now emerging). Jose Parfitt (Pelotas) and Naylor Perez (Bage) leading the research, focused on variety, irrigation scheduling, and fertility issues, as well as rotation into forage system.

São Borja area:
Farrouphilha: Professor Marcelino Knob is researching rice in rotation under a pivot. The rice is just emerging, due to cool weather. There may be some interaction with antecedent crop/herbicides.
Renam Toniazzo: São Borja area, rice looks very good. No disease or weed problems. Good crop last year, expects another successful year.
A first-year Circles for Rice grower farms 2,000 ha of rice at this location with his brother and father. Rice planted in September and looks wonderful - thick and lush. A few spots of clomazone damage, but will recover. Some areas of the field should be monitored for wheel track issues.

São Paolo state:

Lagoa Bonita: volunteer wheat from previous crop dominates the field. They planned to use Aura (profoxydim). I hope it works.
Lagoa Farm: in this field, volunteer edible beans from antecedent crop has taken over most of the field. It is tough to treat, since bordering fields contain both edible beans and soybeans. Volunteer beans are infested with anthracnose, so their agronomic consultant has advised them to wait for the volunteers to die.
First-year Circles for Rice grower: very nice crop, planted in late September. We saw some spots with stunted plants, may be iron chlorosis, zinc, or sulfur shortage.
