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

Rust Mite: 75% of groves infested (Norm 62%); 54% economic (Norm 41%).
Population is above normal and well into the high range for the state as a whole but
varies considerably among groves and districts. It is expected to hold near the current
level. Highest districts are South (2.29) West (2.07) and North (1.83).
Texas Citrus Mite: 27% of groves infested (Norm 31%); 12% economic (Norm 12%).
Population is near the normal low level for this date. Although decrease is expected,
some groves will show increase and a few heavy infestations are likely to occur. Highest
districts are North (.53) South (.46) and Central (.45).
Citrus Red Mite: 30% of groves infested (Norm 38%); 7% economic (Norm 15%).
Population is below normal and in the low range. Gradual increase is expected with
some groves developing heavy infestations. Highest districts are West (.62) East (.55)
and South (.35).
Six-spotted Mite is present in 6% of groves as light infestations only. This is near
normal for this date.
Glover Scale: 75% of groves infested (Norm 79%); 4% economic (Norm 18%).
Purple Scale: 58% of groves infested (Norm 78%); 2% economic (Norm 9%).
Yellow Scale: 75% of groves infested (Norm 65%); 4% economic (Norm 13%).
Black Scale: 20% of groves infested (Norm 33%); 4% economic (Norm 14%).
Chaff Scale: 33% of groves infested (Norm 61%); less than 1% economic (Norm 10%).
The above scales continue to be below normal abundance and in the low to moderate
range in all districts. Little change is expected.
Snow scale is present in 16% of groves and is moderate or heavy in 6% of groves.
Increase is expected.
Whitefly and mealybug populations are below normal and of little importance at this time.
Whiteflies are expected to increase.
Aphids are starting to appear in scattered groves. A strong increase is expected the
last week of March.

Spray Notes: New foliage growth is occurring at the normal time this year but bloom is
expected to occur later than average.
March is a good time to evaluate the nutritional needs of trees and the scab,
melanose, black scale and snow scale situations.
