Farmer Identified Priorities for Potato IPM Research and Extension in Idaho

Part I. Overall (ranked) priorities

#1 develop, adopt, refine, verify, implement and demonstrate systems of thresholds & forecasting for all the key disease, insect, nematode and weed pests;

#2 identify, document and demonstrate (on-farm) the economic and environmental benefits of all recommended IPM practices;

#3 determine the value of crop rotations for pest suppression, soil and plant health, and economic profitability;

#4 develop commercially acceptable varieties with resistance to the major pests (especially aphids, Colorado potato beetle, wireworms, nematodes, early die, early blight, and late blight);

#5 improve pesticide application methods so as to minimize risks to farmer, workers and the general public;

Part II. Specific research and extension recommendations

PEST***	PRIORITY RESEARCH and EXTENSION NEEDS	$ cost/yr	no. yrs
WEEDS nightshade kochia pigweed lambsquarters wild oats	RESEARCH:
	1. derive multi-species injury levels & thresholds to manage concurrent infestation by all 5 species	$50,000	4 yrs
	EXTENSION:
	1. implement via field demonstrations, publications, workshops and particularly decision-support software for person computers	$9,500	3 yrs

INSECTS Colorado potato beetle wireworm green peach aphid loopers	RESEARCH:
	1. develop/implement thresholds	$65,000	5 yrs
	2. develop commercially acceptable resistant varieties	$110,000	10 yrs
	3. develop recommendations for using biological controls (predatory and parasitic insects, microbial agents)	$45,000	4 yrs
	4. develop easy-to-use scouting methods	$25,000	3 yrs
	EXTENSION:
	1. implement via field demonstrations, publications, workshops and particularly decision-support software for personal computers	$9,500	3 yrs

DISEASES late blight verticillium/early die early blight	RESEARCH:
	1a. develop/adopt blight forecasting/fungicide advisory models 1b. ecology/biology of alternate host plants, innoculum sources & cultural controls for late blight 1c. characterize late blight pathogen allozyme genotypes, mating types and fungicide sensitivity	$65,000	4 yrs
	2. determine/document/demonstrate value of crop rotations	$40,000	6 yrs
	3. develop commercially acceptable resistant varieties	$75,000	10 yr
	EXTENSION:
	1. implement/ disseminate via field demonstrations, publications, workshops and particularly decision-support software for personal computers	$25,000	3 yrs

NEMATODES lesion & root knot	RESEARCH:
	1. develop/implement thresholds	$50,000	4 yrs
	2. determine/document/demonstrate value of crop rotations 3. develop commercially acceptable resistant varieties	$75,000	10 yrs
	EXTENSION:
	1 implement via field demonstrations, publications, workshops and particularly decision-support software for personal computers	$9,500	3 yrs

*** pests either are those for which the "Idaho Potato IPM Implementation Team" concluded Idaho potato groweres currently lack IPM tools OR those ranked as "moderate" to "serious" in surveys of commercial growers

Part III. Specific extension programming recommendations

1. Target/tailor training to two distinct audiences: industry field staff/consultants/agchem dealers and salespeople growers & their families & workers
2. In addition to educational outreach already in place (i.e. Extension schools and seminars, printed bulletins, newsletters, and popular articles), desired educational approaches include weekly "pest alert" newsletters/800 numbers hand-held decisions aids (booklets/cards) distance education courses delivered by satellite, internet and related technology
