Recommended Chemical Controls for Mites
READ THE LABEL.
See Table 3.
Rates for pesticides are given as the maximum amount required to treat mature citrus trees unless otherwise noted. To treat smaller trees with commercial application equipment including handguns, mix the per-acre rate for mature trees in 250 gal of water. Calibrate and arrange nozzles to deliver thorough distribution, and treat as many acres as this volume of spray allows.
TO MINIMIZE RISK OF RESISTANCE, DO NOT APPLY A SPECIFIC MITICIDE OTHER THAN PETROLEUM OIL MORE THAN ONCE PER ACRE PER SEASON.
Table 1. Control thresholds and appropriate sample sizes for 10 acres.
|
If the control threshold is: |
Sample Size (Sample trees should be uniformly scattered across a 10-acre block. Do not sample adjacent trees.) |
|---|---|
|
5 mites/leaf |
Examine 4 leaves/tree from 6 trees/area from 4 areas/10 acres = 96 leaves on 24 trees/10 acres |
|
8 mites/leaf |
Examine 4 leaves/tree from 6 trees/area from 3 areas/10 acres = 72 leaves on 18 trees/10 acres |
|
10 mites/leaf |
Examine 4 leaves/tree from 5 trees/area from 2 areas/10 acres = 40 leaves on 10 trees/10 acres |
|
15 mites/leaf |
Examine 4 leaves/tree from 4 trees/area from 2 areas/10 acres = 32 leaves on 8 trees/10 acres |

Abamectin | |||
|
Agri-Mek 0.15 EC + Petroleum Oil 97+% (FC 435-66, FC 455-88, or 470 oil) |
5–10 fl oz + min of 3 gal |
Always apply with a minimum of 1 gal horticultural mineral oil 97+% (FC 435-66, FC 455-88, or 470 oil). Do not apply any abamectin-containing product, (1) within 30 days of last treatment, (2) more than 3 times in any one growing season, or (3) more than 0.047 lb a.i./acre in a growing season. Do not apply in citrus nurseries. |
Rust mites, broad mites, citrus leafminer, Asian citrus psyllids at higher rates. | |
|
12B |
Fenbutatin-oxide | |||
|
Vendex 50 WP |
2 lb |
Restricted use pesticide. Tank-mixing with oil or copper results in reduced residual activity. Do not apply at rates greater than 20 oz/500 gal to fruit less than one inch in diameter within 10 days of an oil spray. |
Rust mites, spider mites | |
|
12C |
Propargite | |||
|
Comite 6.55 EC |
3 pt |
Leaf distortion or fruit spotting may occur when used in the spring or if tank-mixed with oil or applied within 2 weeks prior to or following an oil application. Do not use in spray solution above pH 10. |
Rust mites, spider mites | |
|

Diflubenzuron | |||

Micromite 80 WGS |
6.25 oz |
Do not apply more than 3 applications per season. See restrictions on label. Do not apply when temperatures exceed 94°F. Recommended to apply with 2% horticultural mineral oil. |
