Objective:

 To evaluate the effect of Palisade on lodging when applied at different rates and timings in spring wheat. 

Materials and Methods:

Palisade was applied at 7 oz/A to Egan spring wheat at the tillering (June 1) and flag leaf (June 10) growth stages either as single or sequential applications (Table 2). Treatments were applied using a CO2 backpack sprayer with Teejet XR11002 nozzles in 20 GPA of water and were replicated three times in a randomized complete block design.

Results:

No significant differences were observed for height, lodging, test weight, yield or grain quality.

Summary:

Palisade as single or sequential applications at tillering and/or flag leaf stage had no effect on plant height, test weight, lodging or yield.
