Fungus Gnat Potato Monitor Count Tool

Pool actual potato-monitor counted larvae by known monitor-day exposure, excluding missing evidence; no species confirmation, universal infestation threshold or pesticide recommendation.

Description

Larval monitoring rates need known monitor-day exposure.

Larval monitoring rates need known monitor-day exposure. Missing monitor evidence should not dilute the denominator.^[1]

Enter aligned nonempty integer counts 0–1,000,000, positive days and binary evidence with positive known exposure. Return known count/days, pooled rate and unknown-monitor count.

When to use Fungus Gnat Potato Monitor Count Tool

Use Fungus Gnat Potato Monitor Count Tool when you need to evaluate the supplied records under the calculation and evidence rules below. No species confirmation, infestation cutoff or pesticide recommendation is supplied.

Prepare the measured crop, container, lighting or inventory records requested. Supply verified local catalogs, calibration factors and crop-stage limits; keep units and dates consistent.

How to use Fungus Gnat Potato Monitor Count Tool and understand its results

Prepare the measured crop, container, lighting or inventory records requested. Supply verified local catalogs, calibration factors and crop-stage limits; keep units and dates consistent.
Enter observedPotatoMonitorLarvaCounts, observedMonitorExposureDays, monitorEvidenceFlags using the field table and calculation rules, then run the tool.
Read knownObservedLarvaCount, knownMonitorDays, pooledLarvaePerKnownMonitorDay, unknownMonitorCount. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
observedPotatoMonitorLarvaCounts	Observed potato monitor larva counts	list of number	Required
observedMonitorExposureDays	Observed monitor exposure days	list of number	Required
monitorEvidenceFlags	Monitor evidence flags	list of number	Required

Enter aligned nonempty integer counts 0–1,000,000, positive days and binary evidence with positive known exposure. Return known count/days, pooled rate and unknown-monitor count.

rate=sum(known larva counts)/sum(known exposure days)

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
knownObservedLarvaCount	Known observed larva count	number
knownMonitorDays	Known monitor days	number
pooledLarvaePerKnownMonitorDay	Pooled larvae per known monitor day	number
unknownMonitorCount	Unknown monitor count	number

Limitations and assumptions

No species confirmation, infestation cutoff or pesticide recommendation is supplied.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Days To Germination Vegetable Lookup: A cumulative germination curve can estimate when a selected fraction is reached. Late first observations and incomplete follow-up create different censoring cases. For a complementary task, use Grading Size Class Lookup: Plant grading requires an explicit size-band scheme and observed size evidence. Lower-inclusive edges determine exact-boundary assignments.
