PRODUCT INFORMATION
F9316-2 can be applied in all tillage systems (conventional, reduced and notillage). F9316-2 can be applied in the fall or in the spring as a preplant, pre plant incorporated, preemergence, or early post emergence treatment for susceptible grass and broadleaf weeds in field corn, seed corn, sweet corn and popcorn.

Weed Size:
When applying F9316-2 alone for post emergent weed control, apply before the weeds have reached the maximum height listed in Table 6. Application after weeds have reached the listed maximum height for control could result in commercially unacceptable weed control. For control of weeds in post applications larger than listed in Table 6 and for wider spectrum, apply in tankmixture with herbicide(s) that are labeled for control of targeted weeds. Uniform spray coverage is necessary for optimum performance.

Application Instructions and Timings
Moisture is necessary to activate the active ingredient pyroxasulfone in soil for weed control. Dry weather following applications of F9316-2 may reduce effectiveness. However, when adequate moisture is received after dry conditions, F9316-2 will control susceptible germinating weeds. F9316-2 may not control weeds that germinate after application but before an activating rainfall/ irrigation of at least Vz inch, or weeds that germinate through cracks resulting from dry soil. When adequate moisture is not received after F9316-2 application, weed control may be improved by irrigation. Do not use on peat or muck soils and mineral soils with 10% or more organic matter content. Refer to the crop specific information section for specific application rates, timings and the restrictions and limitations by crop and use pattern. Crop seeds must be planted a minimum of 1 inch deep.

Application Precautions for Post Emergence Applications:
1. If applying F9316-2 post emergence, avoid applications when crop foliage is wet due to heavy dew, rain, or irrigation moisture. If F9316-2 is applied post emergence, shortly before or soon after rainfall, crop response can occur. Recovery from this response is rapid and normal growth is not delayed. Crop yields will not be impacted by this crop response.
2. Do not apply if crop is under severe stress due to drought, cold weather, hail, flooding, water-logged or compacted soil, disease, insect damage, nutrient deficiency (especially low nitrogen levels), or other causes.
3. Do not tank mix any chlorpyrifos containing insecticide with F9316-2 in post applications, as crop response can occur.
4. Do not irrigate within 4 hours of a post emergence application of F9316-2. Rainfall or irrigation within 1 hour may wash F9316-2 off of the weeds during this period and may reduce post emergence performance.
5. Observe all precautions and limitations on the label of each product used in tank mixture with F9316-2.

RESISTANCE MANAGEMENT 
Mode of action 
F9316-2 contains pyroxasulfone which acts to inhibit very long chain fatty acid synthesis as a Group 15 (WSSA)/ Group K3 (HRAC) herbicide. It is a root and shoot growth inhibitor that controls susceptible germinating seedlings before or soon after they emerge from the soil. Any weed population may contain or develop plants naturally resistant to pyroxasulfone and other Group 15 herbicides. Weed species with resistance to Group 15 may eventually dominate the weed population if Group 15 herbicides are used repeatedly in the same in the same field or in successive years as the primary method of control for targeted species. This may result in partial or total loss of control of those species by pyroxasulfone or other Group 15 herbicides.

Resistant Weeds
Some weeds are known to develop resistance to herbicides that have been used repeatedly. While the development of resistance is well understood, it is not easily predicted. Therefore herbicides should be used in conjunction with resistance management strategies in the area. Consult the local or State agricultural advisors for details. If weed resistance should develop in the area, this product used alone may not continue to provide sufficient levels of weed control. It the reduced levels of control cannot be attributed to improper
application timing, unfavorable weather conditions or abnormally high weed pressure, a resistant strain may have developed. To reduce the potential for weed resistance, use this product in a rotation program with other classes of chemistry and modes of action. Always apply this product at the recommended rates and in accordance with the use directions. For optimum performance, scout fields carefully and begin applications when weeds are smaller rather than larger. If resistance is suspected, contact the local or State agricultural advisors.

Glyphosate Resistant Weeds
Some populations of weeds may be tolerant or resistant to glyphosate based herbicides. Applying F9316-2 in a tank mixture with glyphosate for control of emerged resistant weeds larger than specified in table 6 may result in unsatisfactory control. Follow all directions, restrictions and precautions on the EPA-approved label for each product in the tank mixture.
