The Provisia® Rice System was released by BASF in mid-2018. The Provisia® system features a nonGMO herbicide-tolerant rice which allows growers to safely apply Provisia® herbicide and, when used in rotation with a Clearfield® production system, growers have the flexibility of planting a rice-rice-soybean rotation with the option of being able to plant a fourth year of conventional rice. BASF states that the overall advantage of Provisia® is that growers should be able to grow more rice over multiple seasons while rotating different herbicide modes of action whilst simultaneously ensuring sustainable management of all resistant rice types and annual grasses. BASF states that PVL03, the latest rice variety in the Provisia® line, boasts improved blast resistance, a longer kernel length, and shorter stature compared to PVL02. PVL03 is an effective way to control a rice field infested with weedy rice and resistant grasses, restoring that field’s economic efficacy. It has been more than 20 years since the launch of the Clearfield® production system for rice. Until the release of the Provisia® System, no new weed control technology had been introduced that has, according to BASF, the potential Provisia® offers to dramatically helps rice growers overcome yield-reducing weedy rice and resistant grass problems in their fields. The continued adoption of the Provisia® system also sets the stage for growers to begin to shift from simply rescuing infested fields to preventing herbicide resistance in weedy grasses. The latest iteration of rice seed in the Provisia® production system, PVL03, was developed by Louisiana State University AgCenter. PVL03 is a long-grain rice promising potentially good yields, milling and grain appearance-giving it a distinct advantage over earlier Provisia® varieties. Much like the evolution of Clearfield® varieties, the initial Provisia® release- PVL01- made the technology available to growers but had some shortcomings. PVL02 offered significant improvements on yield potential. Another distinct advantage of PVL03 is its strong disease package. Like many of the new Mid-South variety releases, PVL03 contains the Pi-ta gene for blast resistance. This is of critical importance as both PVL01 and PVL02 were very susceptible to the fungal disease. PVL03 also has an ideal kernel length that averages about 7 millimeters, placing it between the shorter length PVL02 (6.5mm) and the very long grain PVL01 (7.4 mm). Much like PVL02, PVL03 also has good tolerance to Provisia® herbicide. According to Horizon Ag, Louisiana trials in 2019 and 2020 showed PVL03 yielding almost 8,500 pounds per acre, outyielding Cheniere and putting it on par with top-yielding Clearfield® varieties like CL153 in the coastal region of the U.S.
