Significantly less control of budworm larvae and damage was obtained with methomyl in early 1970 than in 1968–69, 1971–72, and late 1970. In early 1970, methomyl provided 35 and 25% control of larvae and damage, respectively. In the other seasons, control of larvae and damage with methomyl averaged 82 and 72%, respectively.

When tested in early 1970, carbaryl, endosulfan, monocrotophos, Supracide® (O,O-dimethyl phosphorodithioate, S-ester with 4-[mercaptomethyl]-2-methoxy-Δ2-1,3,4-thiadiazolin-5-one), TDE, and Thuricide HP® ( Bacillus thuringiensis Berliner) also performed poorly vs. the tobacco budworm.

The abnormally low insecticidal control obtained in early 1970 appeared to be related to low rainfall and low relative humidity. Observations suggest that the effects of low moisture on tobacco plants and budworm larvae reduced the effectiveness of insecticides.}, number={1}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={MISTRIC, WJ and SMITH, FD}, year={1974}, pages={99–101} }

The pretransplant treatment of carbofuran provided flea beetle, hornworm, and budworm control for about 10, 7, and 5 weeks, respectively, and the pretransplant plus posttransplant treatment extended this control at least 3 weeks. Aldicarb, disulfoton, and phorate were less effective than carbofuran against flea beetles and inffective against budworms, whereas GC-6506 was ineffective against both of these insects. Aldicarb and disulfoton were ineffective against hornworms, whereas GC-6506 and phorate were not tested against this insect.}, number={2}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={MISTRIC, WJ and SMITH, FD}, year={1973}, pages={480–484} }

Damage was expressed as number of leaves lost. It included (1) the sum of consumed portions of leaves and (2) the number of leaves missing caused by destruction of terminal buds, hereafter referred to as topping damage.

Near maximum damage was recorded for the budworm and earworm at an infestation density of 1 larva per plant. Average damage by the budworm and earworm over infestation densities of 1, 2, and 4 larvae per plant amounted to 7 and 14 leaves, respectively. The higher damage by the earworm was due to greater topping damage.

Damage by the the mixed infestations was greater than that expected from the number of budworms present but less than that expected from the number of earworms present. This fact indicated that the presence of the budworm reduced damage by the earworm. These reductions in earworm damage were due to reductions in topping damage.}, number={1}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={MISTRIC, WJ and PITTARD, WW}, year={1973}, pages={232–235} }

The lower dosages of B. thuringiensis and the virus were usually as effective as the higher dosages, and addition of certain insecticidal and non-insecticidal products to B. thuringiensis spray did not increase its effectiveness. Thuricide®, Biotrol® BTB-183, and Dipel® brands of B. thuringiensis were usually as effective as 1.5 lb/acre of TDE or carbaryl and sometimes as effective as 0.5 lb of methomyl.
