Aspen Leaves As A "Chemical Landscape" For Fungal Endophyte Diversity - Can Nitrogen And Herbivory Shape The Community Composition In Controlled Conditions?, Johanna Witzell, Vicki Huizu Guo Decker, Marta Agostinelli, Carmen Romeralo Tapia, Michelle Cleary, Benedicte Riber Albrectsen

Aspen Bibliography

The endophytic microbiome may influence the ecological performance of plants, including forest trees. Various abiotic and biotic factors may shape the endophyte communities directly but also indirectly, by modifying the quality of host plants as a substrate. We hypothesized that potentially antifungal or fungistatic condensed tannins (CTs) would determine the quality of aspen (Populus tremula) leaves as a substrate for endophytic fungi. By subjecting the plants to nitrogen fertilization (N) or herbivory (H; leaf beetles) we aimed to change the internal “chemical landscape”, especially the CT levels, in aspen leaves. We expected that this would lead to changes in the …

Easy Calibration For Backpack And Canister (Handheld) Sprayers, Cody Zesiger, Kalen Taylor, Corey Ransom, Earl Creech, Matt Yost

All Current Publications

When applying pesticides, fertilizers, and other chemicals, the applicator should know the amount of chemical applied to the treated area. Calibration is a method an applicator can use to measure and set the application rate. If sprayers are not properly calibrated, it can result in over or under application of chemicals, causing damage, reduced pest control, and potential safety concerns. Making the effort to properly mix chemicals and calibrate sprayers can save money and increase treatment effectiveness. This fact sheet provides simple guidelines for calibrating backpack and canister sprayers.
