Pears, Pear Psylla Control, 1977
Insecticide and Acaricide Tests, 1978Abstract Spurs bearing 10-15 psylla eggs were collected from mature Bartlett pear trees in April. In the laboratory each spur was dipped (in and out), 6 replicates each, in each of the insecticides listed and then fixed upright in a flask with the base of the spur immersed in water to keep the spur fresh.

Pear, Pear Psylla Control, 1985
Insecticide and Acaricide Tests, 1986Abstract Single 14-year-old d’Anjou trees were treated on 28 Mar at late-delayed dormant stage for control of pear psylla nymphs. CGA 29170 treatment was reapplied on 9 Apr. Single tree units replicated 4 times in a randomized complete block design were sprayed by handgun to run-off using a 7 gpm John Bean sprayer operating at 350 psi at

Pear, Pear Psylla Control, 1979
Insecticide and Acaricide Tests, 1980Abstract Fifteen-yr-old Barlett pear trees were sprayed with handguns operating at 600 psi to evaluate candidate pesticides for control of pear psylla. Plots consisted of five 2-tree replications in randomized block design. Each plot was sprayed on May 1 and Jun 29.

Pear, Pear Psylla Control, 1987
Insecticide and Acaricide Tests, 1988Abstract Six-year-old pear trees were sprayed by handgun operating at 600 psi to evaluate pesticides for control of PP. Plots consisted of unreplicated blocks 2 rows wide containing 48 trees. The test orchard was sprayed on 6 Mar with Pydrin 2.4 EC, 1 pt/100 gal, and superior type oil, 1 gal/100 gal, to reduce density of overwintered ...

Pear, Pear Psylla Control, 1981
Insecticide and Acaricide Tests, 1982Abstract This test was conducted within a commercial orchard comprised of 9-year-old trees. Single-tree plots were arranged in a complete randomized block design with 5 replications. Treated trees were separated within rows by at least one unsprayed tree and adult psylla were available to repopulate test plots. Treatments were applied on

Pear, Pear Psylla Control, 1978
Insecticide and Acaricide Tests, 1979Abstract Experiments were conducted in a 1.5-acre planting of 6-yr-old ‘d-Anjou’ pear trees. Dilute sprays were applied to single-tree plots with a hand gun and hydraulic sprayer operating at 400 psi. Unsprayed trees were alternated with treated trees within rows. Experiment 1 (Table 1) consisted of 6 prebloom treatments, 5 of which were

Pear, Pear Psylla Control, 1986
Insecticide and Acaricide Tests, 1987Abstract Twenty-year-old pear trees were sprayed with handguns operating at 600 psi to evaluate Avid for seasonal control of PP. Populations were monitored at 2-week intervals by adult and nymph counts. PP adults were counted by the limb tap method (25 taps/plot), PP nymphs and PRM from brushed leaf samples (56 leaves/plot).

Insecticide and Acaricide Tests, 1984
Abstract Twenty-yr-old Anjou pear trees were sprayed with handgund operating at 600 lb/in2 to evaluate candidate pesticides for control of pear psylla. Plots consisted of five single-tree replicates in randomized block design. Pear psylla densities were estaimated by counts of adults and nymphs at about 2-week intervals.

Pear, Pear Psylla Control, 1980
Insecticide and Acaricide Tests, 1981Abstract Sixteen-yr-old Bartlett pear trees were sprayed with handguns operating at 600 psi to evaluate pesticides for control of pear psylla. Plots consisted of five 2-tree replications in randomized block design. Treatments were evaluated by counts of adults and nymphs before the first application and at 2 week intervals for the ...
