The RiceTec FullPage rice cropping solution is a non-GMO herbicide tolerance technology developed through traditional breeding techniques. As such, this technology is only useful as long as it is used appropriately and as suggested under the Stewardship Best Management Practices. Since cultivated rice and weedy rice are genetically similar and compatible, any rice trait technology has the opportunity to be transfer weedy to weedy rice in the event that weedy rice goes uncontrolled.

Therefore, the following stewardship guidelines have been established to help you, the rice farmer, manage this technology so you have the opportunity to take advantage of its benefits for many years to come.

1. Practice sound rotation practices. Crop rotation is one of the most important things you can do to mitigate the development of herbicide-resistant weeds on your farm. Crop rotation provides the opportunity to use different tillage and herbicide modes of action, which can slow the development of resistance. Do not plant FullPage rice in consecutive years in the same field.

2. Start early. Research shows that weed competition during the first one to three weeks of the growing season can have a negative impact on yield. We recommend a preemergence, or delayed preemergence, application of a residual herbicide, such as clomazone, pendimethalin or quinclorac, to slow any weed growth during the critical early stages of growth.

3. Preface™, Postscript™ and Fullscript™ are the only approved formulations of imazethapyr, imazamox and imazamox+quinclorac that may be used with FullPage rice seed. The use of any other formulations of imazethapyr, imazamox or premixes containing these two active ingredients is strictly prohibited.

4. Make a minimum two applications of FullPage rice cropping solution herbicides prior to two-tiller stage. Research has shown that two applications is more effective than a single application at high rates for grass and weedy rice control. Two applications maximize coverage of the weeds and optimizes the longevity of the technology. The first application should take place before planting, at planting or up to three weeks after emergence. The second application should follow 12 to 20 days later for optimum control. We recommend Preface be utilized for the first application and Preface or Postscript be used for the second application. If a third, or salvage application is needed, apply Postscript prior to the panicle initiation (1/2” internode elongation) stage of growth. Applications of Preface or Postscript beyond the panicle initiation stage of growth may lead to yield loss. A sequential Postcript™ program is allowed, but including pendimethalin with the first application is highly recommended to prevent subsequent flushes of red and/or weedy rice.

5. 100% control is the goal. In order to maintain its value and the value of other herbicide tolerance technologies, your goal should always be 100% control of weedy rice to avoid loss of the technology on your farm. Therefore, all considerations should be made to keep weedy rice from flowering and going to seed in your field. Make plans to rogue any weedy rice escapes before heading.

6. Mix things up. Many herbicides in rice are classified as ALS inhibitors. These include herbicides such as Permit1, Grasp2 and Regiment3. Included in this group are Preface, Postscript and Fullscript herbicides. Therefore, we recommend including other herbicides with different modes of action in the tank in order to avoid the development of weed resistance. Herbicides like quinclorac, propanil, bentazon and carfentrazone are herbicides with different modes of action that can prolong the development of weed resistance when tank mixed with Preface or Postscipt.

7. Moisture is the key. In order for most herbicides to be effective, plants need to be actively growing. Dry conditions following Preface applications and prior to Postscript and Fullscript applications can lead to poor weed control. Therefore, make sure that weeds are actively growing at the time of application, and in the case of Preface herbicide plan applications prior to a flush or rainfall for proper incorporation into the soil. Remember, Preface herbicide has a residual soil component that requires activation by moisture within two days of application.

8. Preface before rain, Postscript and Fullscript after. Preface herbicide has both foliar and residual soil activity, which requires activation through soil moisture. Therefore, if your field conditions dictate a flush or rainfall is pending, apply Preface prior to receiving moisture. Postscript and Fullscript herbicide is a foliar herbicide, which does not require soil activation; however, performance is maximized under moist or flooded conditions. Do not apply Postscript to drought-stressed plants.

9. Do not save seed. The FullPage rice cropping solution hybrids are protected by several patents or patents pending and saving of seed for anything other than grain is prohibited.
