Rice Progress and Condition
Rice Acreage Report
USDA released their final planting intensions report today. Mississippi is still reported as having 135,000 acres of long grain rice. Estimated long grain acres in other states are estimated as follows: Arkansas 1,140,000 acres, California 5,000 acres, Louisiana 355,000 acres, Missouri 195,000 acres, and Texas 110,000. The total long grain rice acres in 2012 are estimated at 1,940,000 acres. That is an increase of 146,000 acres or 8% from 2011. Also, this acreage report was 4% higher than the March planting intentions report. This latest acreage report coupled with sluggish export sales has bearish implications on the rice market.

Sprayer cleanout after a herbicide application is a critical component to a successful herbicide application.
Herbicide Drift Is Not What It Use Be
Over last week or so, calls have become to trickle in on sick rice after the flood has been established. In most of these cases, the rice does not want to grow with the fertilizer and a flood on it. After inspecting these fields, signs of herbicide damage are evident on the foliage. When most of the calls come in, the producers believe that it is either a fertility, insect or disease issue. However, those issues generally occur in patches or spots where some areas are worse than others. Herbicide drift usually occurs across the whole field with one side being worse than the other. Also, rice that is on the levee can give you a general direction in where it came from.
