Attune Agriculture conducted 6 trials to evaluate Ampersand's performance with insecticides used to control aphids. The evaluations were administered on a diverse set of crops including row crops (cotton and canola), vegetables (broccoli and peppers), tree crops (pecans) and tobacco.
Aphid Insecticide + Ampersand:*
Improvement in performance
Insecticide + Ampersand:*
Improved control 5 - 6 days post treatment
*Compared to active alone
The evaluations included three aphid species: green peach aphid, cotton aphid and black margined aphid. Leading aphid insecticides were tested including two neonicotinoids (acetamiprid and imidacloprid) and two organophosphates (acephate and dimethoate).
In a trial conducted by RD4Ag in Yuma, AZ, Ampersand was evaluated on canola heavily infested with green peach aphid, nearly 2000 aphid nymphs per 10 leaves. The addition of Ampersand @ 0.25% improved Assail acetamiprid @ 3 oz/A performance 6 days after application on green peach aphid adults by 66.4% and nymphs by 92.3%.
Green Peach Aphid on Canola
In a trial conducted by TRACS in Visalia, CA, total aphids were counted. All treatments provided >80% control. Ampersand added to the tank mix provided average control of 93.2% whereas Admire Pro imidacloprid @ 0.032 lbs ai/A alone provided 85.7% control.
Cotton Aphid on Cotton
Two trials were conducted by RD4Ag in Yuma, AZ, both evaluating Ampersand for control of green peach aphid. In a trial on broccoli, Ampersand @ 0.25% substantially improved aphid control with Assail acetamiprid @ 3 oz/A throughout the study compared to pre-treatment aphid levels. In terms of nymphs, Ampersand provided an average control of 93.3% whereas the insecticide alone provided only 54.1%. In terms of adults, Ampersand provided 70.1% control 6 days after application whereas the insecticide alone only provided 15.6% control.
Green Peach Aphid on Broccoli
In a trial on bell peppers, Ampersand @ 0.25% was tank mixed with either Assail acetamiprid @ 3 oz/A or dimethoate @ 0.65 pt/A. Aphid populations were relatively low and all treatments provided 100% control 3 days after application.
Green Peach Aphid on Bell Pepper
Ampersand @ 0.25% was evaluated as a tank mix with Assail acetamiprid @ 6.9 oz/A for control of black margined aphids on pecans. Ampersand substantially accelerated aphid control compared to the insecticide alone. The Ampersand tank mix reduced adults 81.7% and nymphs 97.4%, 2 days after application, whereas the insecticide alone reduced adults by 36.7% and nymphs by 57.9%.
Black Margined Aphid on Pecan
Eurofins conducted a trial in Cedar Grove, NC to evaluate Ampersand @ 0.25% tank mixed with Orthene acephate @ 0.5 lbs/A or Assail acetamiprid @ 3 oz/A for control of green peach aphid on tobacco. When tank mixed with Orthene, Ampersand increased the nymph mortality 2 days after application by 52.4%. When tank mixed with Assail, Ampersand increased nymph mortality by 73.3%.
