In this project, initiated by Agrinova, IRDA will analyze the profitability of techniques used to repel pasture flies in organic dairy production. Agrinova’s initial project seeks to develop a fly control method that utilizes hydrolats, a by-product of processed essential oils from the region. IRDA's economic analysis will help determine the hydrolat that is most effective in reducing the fly populations that disturb grazing cows. If the selected hydrolats have a known market value, IRDA will assess the costs and revenues associated with each strategy, which include the following: no pest control; insecticide applications; sunflower and water use; and the use of two types of hydrolats. On the other hand, if the market value is unknown, our analysis will determine a selling price that is optimal for the hydrolat supplier and dairy producer alike.
From 2019 to 2021
Pest, weed, and disease control
IRDA's economic analyses help producers evaluate the cost-effectiveness of alternative pest control methods, among other things.
This project was set up to test the nutrient balance sheet method as a tool for estimating phosphorus output from pullets and laying hens.

This project will determine the nitrogen efficiency coefficient (EC) of pelleted laying hen manure, a source that is interesting an increasing number of growers, both organic and conventional, because of its efficiency.
