The best time to spray Monterey Fruit Tree Spray Plus (which is an organic, neem oil-based product) depends on what you’re targeting. Here’s a quick breakdown:

For Preventative Care (Pests & Disease):
Dormant Season (Late Winter/Early Spring): Before bud break to smother overwintering pests and fungal spores.
Pre-Bloom: Just before flowers open, to help prevent fungal issues like scab or powdery mildew.
Petal Fall (Right After Bloom): This is a key time, especially when the tiny fruitlets first start forming—this is often when pests like codling moths, aphids, and fungal infections start becoming active.
After Fruit Set (Post-Bloom):
Yes, it’s a good time to spray—but ideally, you would:
Spray at petal fall and continue spraying every 7-14 days as needed, depending on pest/disease pressure and weather.
Avoid spraying during bloom to protect pollinators.
Early fruit development stage is when insects like plum curculio, codling moth, or fungal issues can get started, so early sprays can prevent bigger problems later.
Key Tips:
Best applied in early morning or late evening to avoid leaf burn and protect pollinators.
Don’t spray during high heat or full sun (temps over 85°F can cause leaf burn with neem oil).

Monterey Liqui-Cop and Monterey Fruit Tree Plus are two different products designed for specific purposes in plant care. Here’s a breakdown of their key differences:

1. Monterey Liqui-Cop:
Type: Copper Fungicide
Purpose: Liqui-Cop is a fungicide primarily used to control a wide range of fungal diseases on fruits, vegetables, and ornamentals.
Active Ingredient: Copper Ammonium Complex (copper soap)
Diseases Targeted: Used to prevent and control diseases like blight, powdery mildew, downy mildew, anthracnose, rust, and more.
Usage: Applied as a spray, it's used both preventively and curatively to stop fungal infections.
Best for: Protecting trees, shrubs, and plants from fungal diseases.
2. Monterey Fruit Tree Plus:
Type: Combination of Insecticide, Fungicide, and Miticide
Purpose: Fruit Tree Plus is a three-in-one product that controls insects, mites, and diseases on fruit and nut trees.
Active Ingredients: Pyrethrins (insecticide) and Sulfur (fungicide/miticide)
Pests and Diseases Targeted: Used to control insects like aphids, mites, caterpillars, and scale, as well as fungal diseases such as powdery mildew, scab, rust, and leaf spot.
Usage: Applied as a spray for comprehensive pest and disease control.
Best for: Protecting fruit and nut trees from both pests and fungal diseases.
Key Difference:
Monterey Liqui-Cop is a fungicide only, focusing on preventing and treating fungal diseases.
Monterey Fruit Tree Plus is a multi-purpose product that controls both pests (insects and mites) and fungal diseases, making it more versatile for tree care.
Choose based on whether you need to target only fungal issues or require broader protection against both pests and diseases.

I purchased this product and the instructions state to use every 7-14 days when the insect pressure is high, but not more than 10 times in a season. It is best to use in the early morning or late afternoon and when the wind is calm. The temperature should be 45 degrees or above.

Following the directions on the container, Its my understanding that it is not too late, as long as the fruit has not been penetrated.

The product label say not to spray on fruit trees when temperatures are above 90°.
