If not, what is the most effective product for SEVERE rust on Plumerias?** A: Once the rust is established, you will need to carefully remove any leaves with visible spots of rust, being very careful not to spread the fungus to non-infected leaves in the process. Throughout the year, pick up all the fallen leaves as well - don't allow them to decompose into the ground. Once you have removed the leaves with more than just a spot or two of orange, you can spray the entire plant, as well as anything surrounding the plant (pot, nearby walls, trunk of plant, etc) with this product and it will help keep the rust in check. I have searched the internet for a magic solution to treat the rust once eatablished and come up empty. Unfortunately, the consensus is that once it's established heavily, it's a process to remove - repeat applications of this every 10 days will help prevent, but not remove existing rust. If you are diligent between now and next summer, picking up leaves as soon as they fall, and some occasional spraying in the spring, and especially leading into the wet season (when you first noticed rust appearing this year) you should be able to prevent another outbreak. I live near Orlando, it's the middle of the summer rainy season, and still no rust yet on my 10 or so plumeria trees. Previous years, by now the leaves were covered in orange spots. **Q: What are the ingredients? Does it contain triforine? Sulfer? Neem oil? other?** A: Myclobutanil is the active ingredient. **Q: How many gallons of dilluted spray (following manufacturer's directions) does this make?** A: To spray it on my roses for powdered mildew disease, I am mixing one ounce of this product with one gallon of water. That is a 1:128 ratio. So a 16oz (1 pt) Immunox bottle can make 16 gallons of spray for me. Other disease treatment may be different (for example, if some requires half dosage, then 32 gallons of spray can be made from one 16oz Immunox bottle). **Q: Do you have the epa registration number for this product? I no longer have the packaging.** A: Sorry but I no longer have this product in my possession. I am using another Spectracide product.

No foliar damage. Fixed an early blight in one night. *by on Reviewed in the United States July 5, 2017* This works. Period. I live in zone 8, and summers are extremely humid. So together with an out of balance good /damaging bugs, for my gardens there will be fungus. No matter how many steps I take for proper garden practices, not over watering, not wetting foliage, no leaving debris on the ground from trimmed plants etc.Anyway, last year was the first time I used it and it saved my gardens. This year, just as helpful . I really had a difficult time deciding with what type of fungicide to choose from . I was considering the copper one. I'm just glad I went with this. Yesterday, there were signs of blight I could just see it on half of my plants . The pumpkin vine leaves were all droopy and the female buds turned brown and died before opening. I sprayed the vine , and the VERY next day it had perked back up with a green female bud visible. Same with my annual flowers .I can spray this properly diluted ratio (I go a little under just to be safe) directly on any plant parts and there has been zero foliage burn. I don't have to spray it directly on the flowers, bc I do not want to harm pollinators. However, without this product , there would be zero flowers /plants for any pollinators and my plant therapy would be no more. I am not even being dramatic.This works. It's safe for garden flowers and plants. Does not cause any browning. Simple and effective . Fact. I keep this stocked (although it lasts a long time with one application, and there are plenty of applications with this concentrate).I use a 32 oz high output regular style spray bottle. This method is certainly less hassle compared with the other styles, excluding mass planting areas. I will include a photo for reference.First picture - this pumpkin would not exist if I hadn't used some spray on the leaves and mainly the female buds that never opened- small, brown/yellow that would shrivel right off. The poor things were just helpless, it seemed nothing could keep them healthy! However, this product did such, ridding whatever fungus present. A week or so later, a robust female flower was able to prosper.Second picture - we had a tail end of a hurricane (2017) come through, which "mashed" this zinnia to the ground. The area was soggy and humid, yet this fungicide prevented fungal infection. Every orange flower is on this one zinnia. This example is fairly odd and unflattering, yet it demonstrates the effectiveness of this product.Third picture- the type of bottle referenced above.Last: balsam impatient plant, day before & day afterLong review but my passion is this right here, and without this product, in my area I would not have thriving plants. ### ⭐⭐⭐⭐ Works great, but use it early and be careful on sensitive plants. *by on Reviewed in the United States March 8, 2013* This product worked as described, but I had a few issues with it. My main complaint is that I think I waited much too long to use it. I decided to first try some "organic' and "home" remedies to control the mold issue I was having in and on potted plants on my lanai. That was my first mistake. While I was dabbling with White Vinegar, and an assortment of other household chemicals, the mold was destroying my plants.By the time I actually had gotten around to applying this product, the damage was quite extensive. The product got to work quickly, but most of the damage had been already done. I mixed the product as described, and immediately noticed a reduction in powdery mildew and mold on the leaves of the plants. Most of them required a second and third heavier application before seeing the mold eradicated completely.I have a wide variety of flowers and each had a varying reaction to this product. Most had little to no reaction to it, however, there were a few that were worth noting. A few of my more delicate orchids definitely had some yellowing of leaves and wilting flowers. They came back pretty strong. What was hit most strongly was my Blue Ginger. I don't think it will ever be coming back. What the mold didn't kill, the fungicide most definitely did.Overall, I would recommend this product with a few disclaimers. First, start at the first warning signs of mold or any fungus, whether it is in the soil, on the leaves, or on the stalks. Second, if using on potted plants, make sure you are mixing the solution exactly. Too much of this product is not a good thing, it will burn up your delicate plants. It is much better to mix it too light, and apply it more often. Mold is resilient! Third, apply secondary precautions to help the fungicide. Remove affected plants, if possible, from others as mold will spread, increase air flow, and increase sunlight. Make sure your potted plants have plenty of drainage! All of these are mold deterrents.Oh, and cover your face both around the mold, and when using this product. Both have shown to be pretty noxious, especially if you have pre-existing breathing issues. ## Frequently Bought Together - Spectracide Immunox Multi-Purpose Fungicide Spray Concentrate For Gardens 16 Ounces, Protects Up To 2 Weeks - Bonide Captain Jack Copper Fungicide 16 oz Concentrated Plant Disease Control Solution for Organic Gardening --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/1093577-spectracide-immunox-multi-purpose-fungicide-for-gardens-16-oz-cures](https://www.desertcart.us/products/1093577-spectracide-immunox-multi-purpose-fungicide-for-gardens-16-oz-cures) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-16*
