Agricultural fungicides, fruit crops, vineyards, ornamental plants, home garden fungicides, agricultural spray drift, and potential food residues

Description:

Myclobutanil is a synthetic triazole fungicide used to control fungal diseases, including powdery mildew, on agricultural crops and ornamental plants. It has also been used in certain home garden fungicide products. Exposure may occur through pesticide application, contact with treated plants, or residues on food crops where its use is permitted.

Health concerns:

Reproductive Toxicity

May alter hormone function and harm reproduction.

Developmental Toxicity

May impact fetal development and birth outcomes.

Organ System Toxicity

May cause organ damage and disease.

Irritant

May cause skin, eye, or respiratory irritation.

Ecotoxicity

May be toxic to ecosystems and wildlife.

HOW MILLION MARKER SCORES CHEMICALS

Million Marker's Ingredient Hazard Scoring uses multiple chemical databases and a science-backed scoring system to compute hazard scores for thousands of chemicals found in consumer products and listed on ingredient labels.

We identified key chemicals based on a database compiling dozens of authoritative sources, screening tools, and QSAR models.

Hazard scores within 11 different health categories (carcinogens, endocrine disruptors, reproductive toxicants, developmental toxicants, genotoxicity, neurotoxicity, organ system toxicity, immunotoxicity, respiratory toxicity, skin/eye/respiratory irritants, and ecotoxicity).

They are weighted based on several factors, including strength of evidence for adverse impacts in humans, severity, and potential contamination.
