NOTE: Only pests or conditions of general or current interest are reported.
Forecasts are for 1 month in advance unless otherwise indicated.

Rust Mite: 70% of groves infested (Norm 59%); 50% economic (Norm 41%).
Population is much above average and in the high range. It will continue high with
25 to 30% of groves having heavy infestations. Highest districts are West (2.15) South
(1.96) North (1.40) and Central (1.30).

Citrus Red Mite: 51% of groves infested (Norm 33%); 24% economic (Norm 10%).
Population is in the moderate range but is much above the average January level of
recent years. Further increase is expected. Highest districts are West (1.31) and
North (1.07).

Texas Citrus Mite: 44% of groves infested (Norm 27%); 18% economic (Norm 10%).
This mite also is in the moderate range and above normal abundance for January.
Slight increase is expected. Highest districts are West (1.62) and North (.70).
Six-spotted mite is below average abundance and very scarce.
Glover Scale: 81% of groves infested; 16% economic. Population is above normal and
approaching the high range with further increase expected. Highest districts are
Central (1.26) East (1.22) and South (1.08).

Purple Scale: 79% of groves infested; 4% economic. Population is near normal and
moderate with little change expected. Highest district is Central (1.07).

Yellow Scale: 68% of groves infested; 14% economic. Population is above normal and
in the moderate range. Increase is expected. Highest districts are Central (1.22) and
East (1.00).

Chaff Scale: 57% of groves infested; 4% economic. This scale is below average abundance
and is currently in the low range. Increase is expected. Highest district is East (.74).

Black Scale: 37% of groves infested; 16% economic. Population is near the normal low
level for January. Increase is expected. Highest district is Central (1.04).
Whiteflies are near average abundance. An increase is expected.

Spray Notes: Although minor elements are commonly applied in prebloom and postbloom
sprays, all elements are not needed every year. For economy in a year of low crop re-
turns, zinc can be omitted until at least some symptoms of deficiency appear. It is not
necessary to use manganese unless persistent manganese deficiency symptoms appear on the
foliage. Spray applications of manganese are likely to be necessary only on calcareous
soils. In groves with acid soils receiving mixed fertilizers, manganese should be
applied as manganese sulfate in the mixed fertilizer. This simplifies the spraying
program, and by reducing spray residue on leaves, tends to decrease the numbers of
insect and mite pests.
