1992- Present

Currently working as a private consultant with Whaley & Steinberg.

A summary of professional experience since 1982 includes diagnosis of causes of agricultural and ornamental plant problems, in field and lab studies, photo and video documentation, sample collection (soil, water, tissue and waste effluent), lab results interpretation, economic loss calculations, report writing and expert testimony. Experience also includes working extensively as a licensed California Pest Control Advisor specializing in Biological Control but also having practical experience with pesticide application, residue sampling, efficacy and toxicity. Other duties have included irrigation and fertility management of many crops grown in California.

1. Pesticide Related Cases:

a. Off-site movement into crops of Urea-based herbicides.

b. Misapplication of pesticides including, Karmex, Eptam, Phenoxy herbicides,

Roundup, Bladex, Treflan, Triazines as well as many fungicides and
insecticides.

c. Misapplication of fertilizers and adjuvents have also been investigated.

2. Pest Management Cases:

a. Isolation from diseased tissue and identification of pathogens from many types of crops and ornamental plants.

b. Eutypa disease of grapevines.

c. Various disease problems of tomatoes, including Phytophthora sp., bacterial

speck and virus diseases.

d. Spanish Measles of grapevines.

e. Phytophthora spp. caused diseases of many perennial crops including Kiwi,

Citrus, Almonds, Walnuts, Cherries and other Stone Fruits.

f. Powdery Mildew disease of various crops.

g. Mealybug damage to grapevines.

moved off site.

b. Determine options for remediation of crop land contaminated with a non-

registered herbicide.

c. Remediation of fungicide contaminated apples exposed to a non-registered

fungicide during packing.

d. Monitoring program for waste effluents related to raisin and winery facilities.

e. Determination of affects of cattle grazing on various species of endangered

plants.

f. Evaluation of cropped and non cropped acreage for agricultural production.

g. Evaluation of affects of using brine waste contaminated ground water on crops.
