TopShot 113 OD

Professional crop protection: field insights on Topshot 113 OD

Managing barnyard grass in rice paddies requires precision, and Topshot 113 OD by DOW AgroSciences has proven to be a reliable component in our chemical control strategy. Its formulation as an oil dispersion (OD) is a significant advantage in the field, as it provides better adhesion to the leaf surface, ensuring the active ingredients—penoxsulam and cyhalofop-butyl—are absorbed efficiently.

Why it works in the field

The beauty of this herbicide lies in its systemic and selective nature. As operators, we value that it targets barnyard grass without causing unnecessary stress to the rice crop. Because it is a post-emergence herbicide, it allows us to wait and see the exact density of the weeds before deciding on the application timing, making our management more sustainable.

Operational parameters

• Dosage: 2.0–3.0 L/ha. We stick to this range depending on the pressure of the infestation.
• Application: Single treatment limit. This makes proper timing critical for success.
• Handling: It is classified under hazard class 3, so standard protective gear is a must, but it doesn't present the extreme logistical headaches associated with more hazardous chemicals.

One essential technical factor to keep in mind is the 60-day pre-harvest interval. Planning is key when incorporating this into the seasonal schedule. For those managing large areas of rice, Topshot 113 OD offers a predictable, consistent performance that makes the harvest process much easier due to significantly lower weed competition.
