Insect Control

NOTE:  For the insecticides listed below, one product trade name and formulation is provided for each active ingredient (common name) as an example of rates, days to harvest (dh), REI, and special instructions. In many cases there are other products available with the same active ingredient. Please see Table 20 and Alphabetical Listing by Trade Name for more information on products with the same active ingredients.

Aphids

For more information see aphids in the Pepper section.

Beauveria bassiana (Mycotrol O): 8 to 32 oz/A (0 dh, REI 4h, Group 22). Treat when populations are low and thoroughly cover foliage. Takes 7 to 10 days after the first spray to see control. Repeat applications may be needed. OMRI listed.

imidacloprid (Admire Pro): 7 to 14 oz/A (21 dh, REI 12h, Group 4A). Can be applied in bedding operation, as a transplant water drench or through trickle irrigation. May be applied in planthouse at maximum rate of 0.44 oz/10,000 plants. See plant-back restrictions. To avoid resistance, do not use another nicotinoid (Group 4A) insecticide if Admire was used at planting.

imidacloprid (Provado 1.6F): 3.8 to 6.2 oz/A (0 dh, REI 12h, Group 4A). For resistance management purposes, do not use a Provado foliar application following another nicotinoid (Group 4A) insecticide application on the same crop. See plant-back restrictions.

malathion (Malathion 57 EC): 1 1/2 pt/A (1 dh, REI 12h, Group 1B).

pyrethrin (PyGanic EC5.0): 4.5 to 18 oz/A (0 dh, REI 12h, Group 3A). OMRI listed.

pyrethrins + piperonyl butoxide (Pyrenone): 1 tsp/gal, or 1 to12 oz/A (0 dh, REI 12h, Group 3A).

Corn Earworms

carbaryl (Sevin XLR Plus): 1 to 1 1/2 qt/A (3 dh, REI 12h, Group 1A).

flubendiamide (Synapse): 2 to 3 oz/A (1 dh, REI 12h, Group 28). Active via ingestion.

indoxacarb (Avaunt): 3.5 oz/A (3 dh, REI 12h, Group 22).

methoxyfenozide (Intrepid 2F): 10 to 16 oz/A (1 dh, REI 4h, Group 18). Insect growth regulator. Works on all instars. Feeding stops within hours but death takes several days.

pyrethrins + piperonyl butoxide (Pyrenone): 1 tsp/gal, or 1 to 12 oz/A (0 dh, REI 12h, Group 3A).

spinetoram (Radiant SC): 5 to 10 oz/A (1 dh, REI 4h, Group 5).

spinosad (Entrust): 0.5 to 1 oz/A (1 dh, REI 4h, Group 5). OMRI listed.

Japanese Beetles

Beetles migrate from turf or pastures starting in July and skeletonize leaves.  Foliage can be protected with spinosad or spinetoram (SpinTor, Entrust or Radiant).

malathion (Malathion 57 EC): 2 to 2.3 pt/A (1 dh, REI 12h, Group 1B).

pyrethrin (PyGanic EC5.0): 4.5 to 18 oz/A (0 dh, REI 12h, Group 3A). OMRI listed.

pyrethrins + piperonyl butoxide (Pyrenone): 1 tsp/gal, or 1 to12 oz/A (0 dh, REI 12h, Group 3A).

Two-spotted Spider Mite

Outbreaks are often caused by the use of broad-spectrum insecticides. Two-spotted spider mites (TSSM) tend to be prone to pesticide resistance. Watch for white speckling on the upper surface of leaves or webbing on the undersurface around leaf veins. Avoid early-season, broad-spectrum insecticide applications for other pests. Use selective products whenever possible. With most miticides (not bifenazate), use 2 applications, approximately 5 to 7 days apart, to help control immature mites that were in the egg stage and protected during the first application. Alternate between products after 2 applications to help prevent or delay resistance. For more information on TSSM see the Eggplant section.

bifenazate (Acramite 50WS): 0.75 to 1 lb/A (3 dh, REI 12h, Group 25).

Stink Bugs

Stink bugs may feed on blossoms, buds or fruit. Bugs migrate into fields from weedy borders in dry seasons. Border treatments are often adequate to manage this pest. Reduced-tillage and increased use of cover crops may increase damage by providing hiding places within fields.  Natural enemies in the field usually contain outbreaks if they are not disrupted by broad-spectrum insecticides.    

carbaryl (Sevin XLR Plus): 1 to 3 pt/A (3 dh, REI 12h, Group 1A).

pyrethrin (PyGanic EC5.0): 4.5 to 18 oz/A (0 dh, REI 12h, Group 3A). OMRI listed.

pyrethrins + piperonyl butoxide (Pyrenone): 1 tsp/gal, or 1 to12 oz/A (0 dh, REI 12h, Group 3A).
