About this file

This is a mix ratio spreadsheet for ground application of insecticide at the Horning Seed Orchard in 2025. The document details the application requirements for Esfenvalerate insecticide (Asana XL or S-FenvaloStar) across multiple orchard units containing Douglas-fir, Western Hemlock, and Western Redcedar trees.

The spreadsheet specifies treatment for 526 total trees across five orchard units (C70, C74, I60, Z01, and Z03), with varying application rates based on tree size. Small trees (164 trees, 10-20ft) require 0.19 oz of formulated product per tree with 2 gallons of water, while medium trees (362 trees, 20-30ft) require 0.388 oz per tree with 4 gallons of water. The total mixture requires 131.10 oz of esfenvalerate, 26.22 oz of R-56 spreader/sticker, and 1,380 gallons of water. Douglas-fir units require two applications, while Western Hemlock and Western Redcedar units require one application with earlier timing.
