A few weeks back, I wrote a post attempting to explain simply in words the difference between current and future corn products offering a reduced refuge. (“Refuge in the Bag: Will that be one bag or two?”)
Sometimes a picture is better than words. This technical piece provides an effective visual of the four products below.
Much better. Thanks team.
UPDATE: I received a comment (see below) that a caption is needed to help explain this concept. Here is an updated note.
The white beans in all the jars represent traited, insect-protected seed. The black beans are the refuge seed. In the first two jars on the left, they are pictured separated because refuge is planted separately in those systems. Farmers have to plant two types of seed products – or two bags – one with traited seed, and one with refuge seed. The numbers on the jar represent the ratio. For example, with VT Triple Pro seed, farmers can plant 80% of their acres to the traited seed, and must plant a separate 20% of their acres to non-insect protected seed.
In the two jars on the right, the black seeds are blended with the white seeds, representing the new “refuge in the bag” concepts. The last jar on the right shows Monsanto’s future RIB complete concept (not yet available) whereby a farmer purchases one seed bag product and the refuge is blended inside in a 95:5 percentage mix.
The jar right of center (labeled Optimum AcreMax 1) has white, black and red beans. The white and black beans also represent a blend – for the corn rootworm trait. Pioneer has said that Optimum AcreMax 1 simplifies refuge. However, the product seems to only simplify for corn rootworm refuge. Optimum AcreMax 1 still requires that a separate 20% refuge be planted for corn borer refuge. That is represented with the red beans and literally represents a second seed product or second bag.
