Break's Historical Context
The discussion opens with a look back at the development of Break, highlighting its initial testing in the 1970s and the eventual registration for use in cotton before expanding to rice and peanuts. This historical perspective underscores the long journey of herbicide development and the ongoing challenges of weed resistance.
Application Guidelines and Risks
Experts emphasize the importance of following label guidelines when applying Break, particularly regarding the timing of applications to avoid crop injury. The risks associated with using Break on cut ground are also discussed, with clear recommendations against its use in such conditions.
Tank Mixing Considerations
The conversation includes a caution against tank mixing Break with ALS herbicides, as this has been linked to increased injury in rice. Current recommendations suggest a waiting period before and after Break applications to mitigate these risks.
Key takeaways
5 things worth knowing
- 01
Break herbicide has recently been registered for use in rice and peanuts, targeting pigweed control.
- 02
Application timing is critical; it should be used on three-leaf rice to minimize injury risks.
- 03
Avoid using Break on cut ground due to potential severe stand loss and yield impacts.
- 04
Tank mixing with ALS herbicides is currently not recommended due to increased injury risks.
- 05
The effectiveness of Break varies by soil type, performing better on silt loam than on clay.
