Research Project: Advancing IPM in Floriculture Crops by Improving Plant Health and Increasing the Use of Natural Enemies

Location: Crops Pathology and Genetics Research

Project Number: 2032-21220-006-16-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2013
End Date: Aug 31, 2018

1) Determine whether adding Bottom-Up regulation to existing Top-Down management strategies for invasive and endemic pests is worthwhile from practical (grower oriented) perspective. 2) Determine if these bottom up management strategies effect natural enemies.

1) Inorganic material silica (as a silicate based fertilizer) and/or microbial inoculants to the soil or soilless mixes will be added to crops and the crops will be monitored to determine if this strategy will increase plant health to the point where antibiosis and antixenosis assist in reducing pest populations. 2)If the first objective determines that leaf thickness/toughness is increased by the addition of silica and reduces leafminer populations, then we will test to see if this procedure will also also effect the ability of commercially available parasitoids (e.g., Diglyphus and Dacnusa) to push through the leaf to parasitize leafminer larvae.
