After wrapping up at the Hoffpauir farm, Barrett and I headed over to Jeff-Davis Parish to take stand counts at the demonstration that Mark Pousson has planted.  The rice is coming along nicely.  At this location, the seed treatments are planted side-by-side in the same cut.  This allows us to easily observe any differences in plant height, vigor, or stand thickness between treatments.  As we were taking stand counts, Barrett observed that if you stood on the edge of the field you could easily see a difference between the untreated seed and the CruiserMaxx treated seed.  I took a few pictures.

Rows of rice grown from untreated seed (no insecticide treatment) in comparison to CruiserMaxx treated seed. The rows are much more visible in the CruiserMaxx treated area.

In the picture above, the untreated area is to the left of the center, while the CruiserMaxx treated plants are to the right.  We don’t know if this will translate to a difference in yield, but it is interesting to note the difference in plant vigor in the early season.

While walking through the field, we also noticed some interesting clusters of eggs.

Barrett held the egg mass in his hand for a closer look.

I’m not sure if these are frog eggs, but that’s what they look like.  This is a nice reminder of the important job that rice fields serve as a home for a variety of wildlife.  It’s a great working environment for a weekend naturalist.

Yesterday Barrett Courville and I took stand counts at the Hoffpauir Demo location that is just southwest of Rayne, La (Acadia Parish).  Boy, it was another beautiful day here in south Louisiana!  The fields are coming along well.  We took stand counts and plant height measurements in Dermacor X-100, Cruiser-Maxx and one untreated cut.  We will be entering and analyzing the data soon.  In the meantime, here are some pictures of the fields. 

Plants grown from Dermacor X-100 treated seed.

Plants grown from CruiserMaxx treated seed.

Plants grown from seed that had fungicide, but no insecticide seed treatments. The flush was starting to move across this field.

The next step with this field will be to scout for rww adults in the days leading up to permanent flood.  If rww adults and scarring are found in the field, we will apply a pyrethroid to two of the cuts at the eastern end of the series of cuts.

Avery Davidson put together a very nice story about the rww demonstration test which aired on TWILA last week.  You can view the video online at youtube by clicking here.  Thanks to Keith Fontenot and Kenneth LaHaye for participating in this interview.  We appreciate the continuing support of the Louisiana Farm Bureau.

The Hoffpauir demonstration site was planted last week.  County Agent Barrett Courville sent me a few pictures of planting.  At this location we will compare an untreated cut to pyrethroid, Dermacor X-100 and CruiserMaxx insecticide treatments.  The arrangement of cuts at this site allowed us to plant multiple fields with each seed treatment.  So, we will get a little more data than usual at this location.

This week, we will most likely be planting three more demonstration sites, one each in the following parishes: Concordia, Jeff-Davis, and Vermilion.  I’ll keep you informed as planting progresses.

At the rest of the sites, we are waiting for the first call to report observation of plant emergence.  I think this cold weather is making the plants lazy.  They don’t seem to want to leave the soil.
