Monterey Neem Oil is an organic liquid pest control spray derived from the seeds of the Azadirachta indica (Indian Neem Tree), which is native to India and other parts of Southeast Asia. Neem has been prized for thousands of years as a pest control product due to its versatile and highly effective properties. It works on contact in multiple ways:
As an insecticide and miticide it works as an antifeedant (insects will stop feeding after they ingest it), as a growth regulator/hormone disruptor ( it prevents normal hormone releases that trigger growth and maturation) and as a smotherant (insects that coated with neem oil will suffocate).
As a fungicide: it will inhibit mycelial growth by coating the spores, which prevents further spore development. will not kill fungal pathogens outright, it will only inhibit further develop, so it's important to treat the area ahead of an infestation.
- Kills the eggs, larvae and adult stages of insects.
- Thorough plant coverage is essential to obtain optimal levels of control.
- Can be used up to the day of harvest - 0-day Pre-Harvest Interval (0-Day PHI).
- Does not require any additional product like a spreader, sticker or extender.
- Controls Alternaria, Anthracnose, Black Spot, Botrytis, Downy Mildew, Needle Rust, Powdery Mildew, Scab, and Twig and Tip Blight. Please see below for a list of insect pests controlled.
For use on roses and other flowers, houseplants, ornamental trees and shrubs, fruits, nuts and vegetables grown in and around the home and in home gardens.
