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: 64% of groves infested (Norm 71%); 42% economic (Norm 47%).
Rust Mite on Fruit: 71% of groves infested (Norm 68%); 52% economic (Norm 47%).
Population is still in the high range and above normal on fruit. Frosty weather
at mid-November started a downward trend which is expected to continue. About 30% of
groves will harbor heavy infestations in December and January. Highest districts are
South (2.06) West (1.71) and North (1.21).

Texas Citrus Mite: 22% of groves infested (Norm 35%); 7% economic (Norm 14%).
Population increased but is still below normal and in the low range. Further ex-
pected increase will result in scattered heavy infestations. Highest districts are
Central (.59) and South (.36).

Citrus Red Mite: 20% of groves infested (Norm 35%); 2% economic (Norm 10%).
Population is at the lowest November level in 18 years of record. Little change is
expected and very few infestations will be important. Highest district is South (.41).

Glover Scale: 51% of groves infested (Norm 70%); 2% economic (Norm 14%).
Population is below average and low. Little change is expected. Highest districts
are West (1.00) and East (.70).

Purple Scale: 46% of groves infested (Norm 67%); less than 1% economic (Norm 7%).
Population will remain below normal and low. Highest district is East (.61).

Yellow Scale: 48% of groves infested (Norm 59%); less than 1% economic (Norm 10%).
Population is below normal and low. Slight increase is expected. Highest district
is East (.74).

Black Scale: 37% of groves infested (Norm 34%); 11% economic (Norm 11%).
Slight increase is expected from the current normal low level. Highest districts
are East (1.00) and Central (.87).

Snow Scale: 14% of groves infested; 4% with moderate or heavy infestations. This scale
is at a record high level for November. Slight increase is expected.

Purple scale, Florida red scale, brown soft scale, cottony cushion scale, pyriform scale,
citrus red mite, grasshoppers and pumpkin bugs are at the lowest November levels in
18 years of record.

Spray Notes: We are now in the season when crops may be harvested on short notice.
It is important that the USDA approved waiting periods between pesticide application and
harvest be observed. Details are given in the 1968 Citrus Spray and Dust Schedule.
