NOTE: Only pests or conditions of general or current interest are reported.
Forecasts are for 1 month in advance unless otherwise indicated.
Rust Mite on Leaves: 74% of groves infested (Norm 61%); 48% economic (Norm 34%).
Rust Mite on Fruit: 74% of groves infested (Norm 70%); 55% economic (Norm 45%).
Population is above average and in the high range. The fall peak is expected
near the end of October but population will remain high through November. Highest
districts are West (2.10) North (1.80) and South (1.76).

Texas Citrus Mite: 13% of groves infested (Norm 27%); 2% economic (Norm 9%).
Population is at the lowest October level since 1956. Although gradual increase
is expected, very few heavy infestations will develop through November. Highest
district is North (.50).
Citrus Red Mite: 29% of groves infested (Norm 32%); 87. economic (Norm 8%).
This mite is near the average population level for October. Continued increase
is expected but most infestations will be light to moderate. Highest districts are
North (.75) and West (.50).

Yellow Scale: 66% of groves infested; 14% economic. Population continued to increase
and is.at a record high level. Little change is expected from current abundance. All
districts are in the range of .75 to .92 but Central district (.86) has more economic
infestations (287.).

Glover Scale: 57% of groves infested; 8% economic. Population is near the average
moderate October level of recent years. Little change is expected. Highest districts
are East (.82) and Central (.76).

Purple Scale: 60% of groves infested; 4% economic. Population is slightly below the
average October level. Infestations are light to moderate in all districts and little
change is expected.
Chaff Scale: 36% of groves infested; 3% economic. Population is below normal and
at low level in all districts. Slight increase is expected.

Black Scale: 31% of groves infested; 7% economic. Population is near the low level
normal for October and little change is expected. A few heavy infestations still
remain in the North and Central districts.

Whitefly: 67% of groves infested; 12% economic. Situation is normal and moderate
with little change expected.

Spray Notes: Heavy infestations of rust mite will continue to occur and should be
controlled promptly. With sulfur, chlorobenzilate or zineb at the usual rates, no
waiting days are required between application and harvest. Most of the combination
miticides for controlling rust mite and spider mites have some restrictions on the
time of use or harvest. Growers and harvest supervisors should become familiar with
these restrictions.
