For the last few years, multiple areas throughout the South, but especially south Louisiana, south Arkansas, and northeast Arkansas, have been in a crisis mode dealing with ALS-resistant weedy rice and grasses. The Provisia® Rice System was developed to address this crisis as well as to extend the life of Clearfield rice. The Provisia Rice System is the ideal companion system to the Clearfield® Production System for rice, providing farmers with another effective tool to manage weedy rice, providing farmers with another effective tool to manage weedy rice, red rice, and grasses that have developed resistance to multiple modes of action.

PVL04 (NEW)

FIRST ARKANSAS-BRED PROVISIA® LINE

New PVL04 is the first Provisia Rice System variety developed by the University of Arkansas breeding program. Multi-state tests show that it performs similar to PVL03 in the Coastal Region and better in the Northern Delta Region. It contains the Pi-ks and Pi-ta blast-resistant genes and has shown very good straw strength. PVL04 matures about two days later than PVL03 and, like PVL03, it has excellent package quality.

  • This variety has genetic markers for Pi-ta, which confers resistance to the following blast races: IA45, IB1, IB49, IB54, IB45, IH1, IG1, IC17, IE1.

*Reactions may differ due to variability of strains among pathogens.

  • 1 Seed/lb is not an exact number; it is an average from multiple samples harvested over a wide geography.
  • 2 Seeding rate is a suggestion based on drill-seeding in ideal conditions and fungicide/insecticide treated seed. Planting non-treated seed is not recommended. Seeding rate should be increased by a minimum of 10 lbs/A when using non-treated seed, planting into a rough seedbed, water-seeding, high-pH soils and soils with salinity issues.
  • 3 Nitrogen rate is a suggested rate based on a two-way split nitrogen application with the first application being applied on dry soil.
