== Overview ==

The Rust Mite tool helps monitor the migration risk of rust mite (Calepitrimerus vitis) and blister mites (//Colomerus vitis//). The tool utilizes temperature data to predict activity, enabling users to time treatments effectively. This guide explains how to interpret and use the graphs to manage these vineyard pests.

	5	== 1. Understanding the Risk Overview Table ==
	6
	7	=== Purpose ===
	8
	9	The Risk Overview Table provides data on the potential migration of rust and blister mites. Key components include:
	10
	11	* Date Row: Grey-highlighted cells mark the forecast period.
	12	* Temperature Sum (Kelvin Days, Kd): Displays the accumulation of daily average temperatures starting from March 1.
	13
	14	=== Key Thresholds ===
	15
	16	* 300 Kd (Yellow): Migration becomes possible.
	17	* Warm Days >10°C (Red): Signals active mite migration, making it the ideal time for treatment.

	21	== 2. Interpreting the Graphs ==
	22
	23	The graphs cover a three-week period:
	24
	25	* Two weeks of historical data
	26	* The current day
	27	* The forecast period
	28
	29	=== Graph Components ===

	32	Risk and Temperature Data
	33
	34	* Temperature Sum Curve: Displays the accumulated percentage of the threshold value. The curve resets to 0% when the calculation concludes.
	35	* Risk Bar: Represents migration risk using colors corresponding to the thresholds described in the legend.
	36	* Migration Start Date: Displayed on the graph if conditions for migration have been met.

	38	1. (((
	39	Weather Data

	41	* Includes daily averages for:
	42	** Temperature
	43	** Precipitation
	44	** Humidity
	45	** Leaf wetness is shown in blue at the bottom.

	47	1. (((
	48	Model Parameters
	49
	50	* The background of the temperature sum curve is overlaid with grey bars representing accumulated daily average temperatures.
	51	* The graph indicates when migration conditions were first met.

	56	== 3. Practical Application ==
	57
	58	To use the graphs effectively:
	59
	60	1. Monitor Temperature Sums: Track when the 300 Kd threshold is reached and warm days (>10°C) occur.
	61	1. Plan Treatments: Schedule treatments during active migration (red-marked days) for maximum effectiveness.
	62	1. Analyze Weather Data: Assess environmental conditions to determine their impact on mite activity.
