We tested Pradia as a foliar and three different drench rate applications, as well as KleenGrow as a foliar application, to suppress green peach aphids on potted pansies.
Pradia as a foliar application may have provided greater suppression by 3 days after treatment compared to the drench applications; however, all Pradia treatments (all drench rates and foliar application) provided very good suppression (>95%) of green peach aphids by 7 days after treatment.
KleenGrow provided suppression of aphids by 3 days after treatment (~50%), which resulted in reduced aphids throughout the trial.
Presentation delivered on October 31st and November 1st to greenhouse vegetable growers. Aimed specifically for whitefly, aphid, and twospotted spider mite management using biological control and a quick look at insecticide compatibility resources.
Presentation delivered through webinar as a part of the “All Bugs Good and Bad Webinar” series. This presentation gives some basic biological of aphids, scale insects and whiteflies and how to find resources to manage them.
There have been several reports of woolly aphid infestations in East Texas within the last few weeks. Woolly aphids are often described as being small white flying insects found on leaves. Just like all other aphids, they penetrate leaf veins and feed primarily on the phloem. In doing so, they excrete a lot of the excess phloem in the form of “honeydew” – a sugary solution which often ends up on nearby leaf surfaces or on the ground near the infested tree. A high level of infestation often results in a sticky ground and grass below the infested tree and the appearance of black sooty mold where honeydew has coated a surface. Black sooty mold will appear as a satin bumpy black substance (hence the name “sooty mold”) on the honeydew-coated surface. Continue reading “Woolly Aphids”
Originally created for the Texas Nursery and Landscape Association 2014 Expo, this presentation outlines five common pests found in greenhouse ornamentals and turf crops, how to monitor them and management strategies, as well as informing growers about new invasive insects they should keep their eyes open for.
There are thousands of species of aphids and any grower that tells you they don’t have them must not get out much. Aphids reproduce at an alarming rate, with newborn aphids already developing embryos the moment they are born. Apparently they are in a rush! This is a 30-minute slideshow on aphids and their control.
