Brazil call for soybean rust measure
Researchers, seed suppliers and growers in Brazil’s major soybean-growing state of Mato Grosso are backing proposals to almost double the fallow period between harvests to avoid increasing resistance to fungicides. Concern over resistance to products for the control of Asian soybean rust (Phakopsora pachyrhizi) is behind the move. The state employs a 90-day policy in which no planting is permitted from June 15th to September 15th (Agrow passim). The Mato Grosso plant health commission, the CDSV/MT, has approved a proposal extending that by two months, running from April 15th. The measure would require the support of the plant health agency, the Indea, to become a regulation. CDSV/MT brings together various suppliers, growers and researchers.
