Herbicides Trials

The Fayette Co. herbicide trial was severely affected by weather, but weed control trends are evident in the weed pressure rating. Command alone was week on pigweed as expected. Adding Spartan improved control. Command alone or in combination with Spartan provided excellent control of common ragweed. Spartan alone or in combination with Prowl or Command gave excellent control of pigweeds, yellow nutsedge and morningglories.

Fungicides Trials

Blue mold pressure was severe while black shank pressure was mild. Ridomil down followed by an experimental chemical at the 1st cultivation followed by Ridomil at the 2nd cultivation or layby was significantly better than the check.

All blue mold treatments were measurably better yielding than the check, but only the Acrobat, experimental at 8 fl oz/a over-the-top, the experimental at 12 fl oz/a and the experimental rotated with Actigard were significantly better. Actigard alone did not look as good as it can due to the severe blue mold damage prior to the plants reaching the label required 18” height.

Insecticide Trials

Weather influenced both insecticide trial, but the Boyle Co. location recovered to produce good yields. The high rates of both Admire (7 oz/a) and Platinum (8 oz/a) produced the best vigor and lowest percentage of colonies of aphids with the lowest incidence of aphids per colony. Adding Orthene did not improve results, but could help with cutworms which were not evaluated in this test. However yield although measurably different were not significantly different.

Weather was too severe in Wayne County to draw any conclusions.

Two treatments each with number equal to fl oz/a rate of Denim. Trial was severely compromised by weather.

Growth Regulator Trials

Several growth regulators were applied at different time to tobacco to determine possible effects. Heavy rainfall may have obscured any potential results. Reducing the rate of nitrogen significantly affected yield while adding Vitazime did not maintain yields similar to that where 250 lb/a nitrogen was applied.
