Growers know all too well that hot and dry conditions can contribute to yield loss in corn and soybean crops, especially when these stresses last for a prolonged period of time. Terramar gives growers the opportunity to mitigate the effects of these weather-related stresses so that their crops can hold on to their yield potential.
There are two key opportunities for making a
Terramar application on corn and soybeans.
The first opportunity to apply
Terramar is with the early post herbicide pass, typically at the V4-V5 growth stage in both crops. The second opportunity—one that is approaching soon—is with a fungicide or foliar plant nutrition pass on corn and soybeans. For those who have already applied
Terramar earlier in the season, a two-pass program (first at the early vegetative growth stage, then at the reproductive stages) may be beneficial, particularly if crops are under prolonged stress.
In corn and soybeans, the window for applying Terramar with fungicide or plant nutrition products is:
- Corn - V10 (early season) through R3 (tar spot)
- Soybeans - Pre-bloom through R3
All Terramar applications made at reproductive stages should be at a minimum rate of 1 quart/acre. Applications can be made by airplane, helicopter or a ground rig.
Below are two examples of recent trials in which Terramar was applied at reproductive stages in corn and soybeans, leading to yield increases compared to the grower's standard practice.
