Alfalfa: The lesser of two weevils.

Alfalfa: The lesser of two weevils.

I found small Alfalfa Weevils in two different producers’ alfalfa fields today. This is very early for the weevils to get started, but there they were! The weevils were very small and mostly buried in the bud of the plant but you might want to be alert for this pest.

The last two years we have had a difficult time killing weevils. However, this year we have some moisture for the crop to work with and hay is worth more than ever. I would think we as producers would want to take care of the crop by killing these pests early.

Since the weevil are breaking early it is VERY probable we will have to spray the crop more than once to get to the first cutting. To that end one suggestion would be to use the relatively cheaper (approx. $10.00/Acre applied) chemistry now (pyrethroid with Lorsban spike) and the longer residual more expensive chemistry later as needed. I repeat it is very likely we will need two sprays with different modes of action and residual!

With the value of hay it is a very small price to pay.
