How to Scout your Milo field for headworm threshhold.
Thresholds for spraying milo are 1-2 worms per head from flowering to soft dough stage. The yield loss will be roughly 5%. The best sampling technique for this is the bucket method. Take a 5 gallon bucket and shake 10 milo heads vigorously from 3-4 locations throughout the field. (See attached photos) Count the worms and divide by the amount of heads tested to obtain the threshold. Small to 3/4 inch worms have the highest feeding rate while 1-1 1/2 inch worms are close to pupating and will feed less. We recommend applying Lambda, which is a generic form of Warrior Insecticide.

How to Scout your Soybean field for numerous worm threshhold.
To scout for damage in soybeans, watch leaves for feeding. If you see 30%-40% foliar feeding/leaf damage, it is an indication they may move to pod feeding. Once the bean pod has been fed on, the plant will not continue filling that pod. We recommend applying bifenthrin, which is a generic form of Hero or Capture. (See photos in Gallery)
K-State recommends using Generic Fungicide and has for the last five years and counting on Stripe Rust. Studies have shown 15-20 bushel gains per acre on treated wheat. The cost savings over branded products is about $10.00 per acre or more. Timing for Fungicide application is after flag leaf is fully emerged through the bloom. In recent yearly studies, all fungicides lasted about 20 days before tapering off in residual. There is a 30 day Pre-Harvest Interval on Generic Fungicides.
