The environmental conditions that favor uptake are adequate soil moisture and relatively high humidity. Soil temperature should be above 40 degrees F for trunk injection. Hot weather or dry soil conditions will result in a reduced rate of uptake so trees should be watered thoroughly if applications are made when soil is extremely dry. If treating trees in the summer, inject in the morning for the quickest uptake. Tree health will also affect treatment efficacy, so assess tree health prior to treating.

This can reduce photosynthesis, weaken the plant, and eventually contribute to the plant\u0092s death. In addition, feeding can cause the plant to ooze or weep,&nbsp; resulting in a fermented odor, and the insects themselves excrete large amounts of fluid (honeydew).

To increase the resilience of the tree, we recommend a follow up application of NutriRoot\u00ae or Mn-jet Fe\u0099. Mid-summer (July) treatments typically coincide with the arrival of 4th instar (red) nymphs and adults on host trees. SLF mortality occurs after ingestion, generally within a few days of treatment application, and continues for a full season. Adults may continue to migrate to attractive treated trees into the fall, but feeding is limited and honeydew and sooty mold production will decline.<br><br><\/li><\/ul><div>&nbsp;&nbsp;<\/div><div><a href=\"javascript:void(0);\"><strong>References And Photo Credits<\/strong><\/a><\/div><ul><li>Reference USDA APHIS<br>Photo credits Virginia Cooperative Extension<br><br><\/li><\/ul><div>&nbsp;<\/div>","image_name":"012-scaled.jpg"},{"id":"39","pest_name":"Thrips","pest_description":"<div><strong>Thrips are slender, tiny insects that often have fringed wings and are generally 1 mm or less in size.<br><\/strong><br><\/div><div>Nymphs are elongate, lack wings and range in color from off-white or yellow to brown or black.

Extra caution must be taken when treating trees in hot (&gt; 90?F) conditions, as doing so may result in an adverse reaction for the tree.
