Rice insecticide seed treatment considerations for 2012

We have had quite a few inquiries about using a combination of seed treatments, neonicotinoid and Dermacor X-100, in rice. While this practice is legal, using more than one seed treatment is not a practice that we encourage in most circumstances because it results in more insecticide use in rice production than may be necessary. Read on to learn more about the current situation.

EPA approval of a Section 24C registration for use of Dermacor X-100 in water-seeded rice in Louisiana

I just received word from Bobby Simoneaux, Louisiana Department of Agriculture and Forestry, that the EPA approved a Section 24C (special local need) registration for use of Dermacor X-100 in water-seeded rice in Louisiana.

Rice water weevil demonstration program results – 2011

Rice water weevil (RWW) management demonstrations have been conducted for the past four field seasons. The purpose of these demonstrations is to evaluate currently recommended insecticides on commercial rice farms in Louisiana to control RWW. These trials are a joint effort between county agents, farmers, consultants, seed dealers and chemical distributors. In 2011, we compared three insecticide seed treatments (CruiserMaxx, Dermacor X-100 and NipsIt INSIDE) to an untreated check.

Colaspis confirmed in Jefferson Davis Parish

This morning I admired the moon setting over University Lakes on my way into campus. Wait a minute, I was biking into campus by moonlight? Yep, a sure sign of field season – early mornings and long (but exciting) days. Today we headed down to Jefferson-Davis Parish to scout a couple of fields that were suffering from stand loss due to an unknown cause. In one location we are still trying to determine the cause. In the second field we scouted we confirmed a fairly severe colaspis infestation. We met with Farmer Kyle Fontenot, Consultant Ron Smith and Nicky Miller at the field which is located between Hathaway and Elton.

More chinch bugs and a reminder about pest spectrum of rice insecticide seed treatments

This morning I received another call about chinch bugs infesting seedling rice – this is the fourth call I’ve had this season, so I want to remind field scouts to be on the look-out for this pest. So far they have been reported in Jeff-Davis, Evangeline and St. Landry Parishes. In this blog posting I also provide a reminder about which insects are controlled by the different seed treatments.
