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: 647. of groves infested (Norm 56%); 39% economic (Norm 35%).
Rust Mite on Fruit: 67% of groves infested (Norm 68%); 51% economic (Norm 44%).
Population recently increased to above normal level on both leaves and fruit.
Further increase will occur and population is expected to continue in the high range
through October. Highest districts are W st (1.70) South (1.58) and North (1.30).

Texas Citrus Mite: 9% of groves infested (Norm 24%); 4% economic (Norm 8%).
Population is below average and in the low range. Although gradual increase will
occur in October and November, very few infestations will be important. Highest
district is North (.36).

Citrus Red Mite: 24% of groves infested (Norm 32%); 87. economic (Norm 87.).
Population is in the low range and slightly below normal. This mite will increase
in October and will hold near the average fall population level. Highest districts are
North (.65) and West (.43).

Yellow Scale: 60% of groves infested; 13% economic. Although population declined in
August and early September, it was the highest reported for those months in 15 years
of record. An upward trend began in late September and is expected to continue
through October. Highest districts are Central (.89) North (.79) and West (.77).

Glover Scale: 50% of groves infested; 8% economic.
Population is currently normal and in the low range. Increase is expected.
Highest districts are East (.75) and Central (.70).

Purple Scale: 51% of groves infested; 27 economic. This scale has recently become
more common but very few infestations are expected to become heavy. Highest district
is West (.80).

Chaff Scale: 31% of groves infested; 2% economic. Slight increase is expected from
the current low level. Highest district is East (.50).

Black Scale: 35% of groves infested; 10% economic. Population has dropped below the
normal fall level but this scale is still numerous in scattered groves. Little change
is expected. Highest district is West (.80).

Whitefly: 70% of groves infested; 12% economic. Little change is expected from the
present normal moderate level.

Mealybug has decreased to low level but is still above normal abundance.

Spray Note: Rainy weather favors development of brown rot. If this disease appears,
a spray containing 3.5 lbs of 53% tribasic copper sulfate (or equivalent) per 500 gal
applied immediately to the entire tree will give some control.
