Rice Water Weevil, 1980

Insecticide and Acaricide Tests, 1981
Abstract Rice was planted in Crowley silt loam May 9 and flodded June 13. Three tests were each arranged in a randomized complete block design with 3 (Test 2) or 4 (Test 1 and 3) replications. Granular treatments (Test 1) were applied with a hand shaker just prior to flooding on June 13 to plots 3.5 x 15 ft.

Rice Water Weevil Control, 1982

Insecticide and Acaricide Tests, 1984
Abstract Insecticides were evaluated in five experiments at the Rice Res. and Ext. Cent, in Stuttgart, Ariz. Rice was planted in Crowley silt loam: ‘Starbonnet’ on 11 May for tests I to IV and ‘Lebonnet’ on 8 June for test V. Each test was arranged in a randomized complete block design with four (Tests I and II) or three (Tests III to V)

Rice Water Weevil Control, 1981

Insecticide and Acaricide Tests, 1982
Abstract Rice was planted Apr 28 in Crowley silt loam at the Rice Research and Extension Center, Stuttgart, AR. Both tests were arranged in a randomized complete block design with 4 (Test I) or 3 (Test II) replications. All plots were sampled for root-feeding larvae by taking 5 soil cores (9 cm dia x 7 cm deep) from the drill rows of ...
