Cattle grazing-read label Benomyl used alone may aid the development of resistant strains of diseases especially pecan scab.

Increase vol/tree as foliage grows. Alternation of insecticide throughout season is suggested to avoid outbreak of secondary pests.

Spray for aphids and mites only if avg. of more than 30/compound leaf, if sprayed previously for nut catebearer, do not repeat.



If weather is rainy, apply fungicides at 2 wk intervals or increase rate by 1/2. Combinations of insecticides tank mixed may be necessary to control all pests present.

Check nuts for shuckworm damage spray either #4,7,9,10,15,23,27 or 29 if present.

Apply second and third shuckworm spray at 2 week intervals after first spray.


S,DS,BLS, Aphids and mites may build up if
PM,A,M,HS,W Sevin is used for W. Monitor and
spray if numbers of aphids exceeds avg. of 10/compound leaf. Sample
randomly throughout the orchard.

S,DS,BLS, Do not apply after shuck split. The
PM,M,A,HS,W advantage of controlling late season
foLiar diseases is currently controversial. Therefore, an early to midSeptember fungicide application could
be beneficial.


1If different pesticide formulations are used, they should be used at an equivalent amount of actual toxicant/acre. Tank mixes of different compounds should be tested in small amounts before filling tank. 2BLS=brown leaf spot, DS=downy spot, NB=nursery blight, PM=powdery mildew, S=scab, A=aphid, HS=hickory shuckworm, LC=leaf casebearer, M=mites, NC=nut casebearer, P=phylloxera, SB=spitttebug, W=weevit, FW=fatl webworm/watnut caterpillar.
3This schedule is considered prophylactic and does not consider the improvements and savings that can be gained by scouting of orchards for the detection of pests. We strongly recommend the use of scout information to reduce the application of pesticides. 4For more detailed information consult the FAIRS computer program which is accessible through your local county extension office.
