The following images were taken July 16 in Wilson county. In Image 1 the timing is appropriate for Apogee. In Image 2, peanuts are several days away from being ready for Apogee. Peanuts in Image 3 most likely will not be ready until late next week.
Image 1 is from the grower’s field next to the plots. Image 2 was from our plots and had a good insecticide program to control thrips. Image 3 was not treated with insecticide at planting or with acephate. The delay in development is due to thrips feeding.
Don’t forget the nitrogen with these applications. Also, growers are spending a great deal of money even for a single application, so they need to apply the material when they have a window of 6-8 hours before rain. While prohexadione calcium and mepiquat chloride serve the same function (peanut versus cotton), Apogee is much more expensive than Pix. A repeat application after wash off would be economically painful. Including crop oil concentrate with Apogee and nitrogen often improves product performance over nitrogen alone. This might increase the rate of absorption when concern exists about rainfall and wash off.
Dewayne and I will have a number of plots for you to look at with Apogee later in the season.
