 RootShield Home & Garden FAQ

Why should I use RootShield Home and Garden?
RootShield works to prevent certain root diseases that are commonly a problem in the landscape and garden. It is not a chemical. It is natural, non-toxic and effective if used according to the label. 

How does RootShield Home & Garden work?
It attaches to the plant’s roots taking up the space that disease organisms need in order to attack the plant. It feeds on the materials exuded by roots that attract root disease pathogens eliminating this food source for disease pathogens. RootShield will seek out and feed on disease pathogens in the soil.  

Is it safe to use your products inside?
Our products are safe to use indoors when the label instructions are followed.

What plants can I use RootShield on? (indoor and outdoor)
RootShield can be used on any living plants with a root system.

What diseases will it control?

RootShield will prevent Pythium, Fusarium, Rhizoctonia, Thielaviopsis and Cylindrocladium root diseases.

 

Will it kill the disease?

RootShield’s main job is preventing the disease organism access to the plant roots before the plant is sick. It will not cure a diseased or sick plant. It protects healthy plants.

 

How do I apply it?

No special equipment is required for applying RootShield. A bucket to mix the product with water and a measuring cup for drenching will suffice. It can also be applied with liquid fertilizers.

 

How will I know if it is working?

Healthy disease-free plants with healthy root systems will be a sign that RootShield is protecting your plants. Since RootShield is protecting the roots, you may not see obvious signs.

 

How do I know what kind of disease my plants have?

Contact your local Extension Agent for help in identifying plant diseases. They can refer you to the nearest plant diagnostic lab.

 

Will your product hurt my pets or kids?

Do not allow children or pets to be exposed to the product during mixing or application, as is the case for all pest control materials (biological or chemical). RootShield is rated by the EPA as a very low toxicity product. Allow the application area to dry.

 

How long will it last – in the container? – on my plants? – when mixed in water?

RootShield will last for the current season or about 6 months.

In the soil, RootShield will last 10 to 12 weeks for plant root protection. 
When mixed with water, RootShield should be stirred regularly during application immediately following mixing. Do not store RootShield mixed with water.

 

Where can I store your products?

RootShield should be stored in a cool (750) dry area.  Freezing temperatures will not harm the product.

 

What’s the best time to treat my plants?

When using RootShield, treat plants as early in the growing cycle as possible before they are contaminated by disease pathogens.

 

What are common mistakes made when using your product?

Common mistakes include:

  1. Applying RootShield when disease is already a problem in your plants.
  2. Improper storage of product (in conditions that are over 75oF or holding past the expiration date on the container).
  3. Using RootShield to control diseases that are NOT covered on the RootShield label.  

I mixed up 1 gallon and only used ½ gallon – what do I do w/ the rest of the stuff left over?

The remaining solution can be applied to other plants in your landscape or garden. Properly rinse (triple rinse with clean water) all buckets, measuring cups, etc. after use. Properly dispose of all RootShield containers.

 

I got some of your product on my tomatoes – is it safe to eat or do I need to throw them away?

RootShield has a 0-day preharvest interval so it is safe to eat fruits and vegetables exposed to RootShield. All fruits and vegetables should be washed before eating.

 

Do I have to wear gloves and long pants when using your product?

It is recommended that gloves and long pants be worn no matter the material being mixed for any disease or insect pest application. The RootShield Home and Garden EPA label does not state that gloves and long pants are required.  

 

I spilled some of your product on the cement/grass/deck – what should I do?

If the spilled material is dry it should be swept up and properly discarded. If liquid, the material should be blotted up with an absorbent material and properly discarded.

 

My plants were dying and I used RootShield.  Why didn't it work?

RootShield is a preventative material only. It will not cure dying plants and this type of application is not included on the RootShield label.

 

How does a fungus eat a fungus?

RootShield blocks pathogens from occupying the space near or on the root zone (Squatter’s Rights) and actively attacks and kills diseases that are trying to damage the roots.

 

How long will it stay living in my soil?

RootShield starts immediately protecting propagated plants or seeds, resulting in fewer plant losses. It also protects against secondary infections resulting from insect damage of the roots. Apply RootShield every 3 months to secure an adequate “defensive” barrier around the roots.

 

What are the rates for using RootShield?

1.  For Drench application to seeds mix 1 to 3 tablespoons of RootShield per gallon of water and apply with a watering can or other device to 25 feet of planting furrow before covering seed with soil.

 

2.  For transplants mix 1 to 3 tablespoons of RootShield per gallon of water and apply ½ to 1 cup (4-8 fl oz) per plant at transplanting. For new plant beds mix 1/3 tablespoons of RootShield ad apply at a rate of one gallon per 25 square feet.


3.  For established beds or potted plants mix 1 to 3 tablespoons of RootShield per gallon and apply at a rate of one gallon per 25 square feet of plant bed or ½ to 1 cup (4-8 fl oz) per 4 to 8 inch pot.

   

 MilStop - FAQ

 

Why should I use MilStop?

MilStop is an effective curative fungicide for powdery mildew, and preventative for downy mildew and many leaf spot diseases. There is no known resistance to MilStop - that makes it an excellent disease management tool as a stand-alone fungicide for foliar disease control or alternated in rotation with other fungicides.

 

When I mix up MilStop it foams – is that OK?

Yes, let the mixture set for a few minutes and the foam will go back into solution.

 

How does the high pH of MilStop affect my plants?

The pH of MilStop will not adversely affect plants.

 

I sprayed my plants with MilStop and it didn’t work – why not?
There are several possibilities that could be the cause:

  1. If your plants were dying before the MilStop application, the material was not applied soon enough.
  2. MilStop was not labeled to control the plant disease causing the damage.  
  3. Disease pressure was too high or the disease was too well established.
  4. MilStop was applied too infrequently.

I sprayed my plants with MilStop, and then it rained. Will it still work or do I need to spray again?

You will need to increase applications during periods of rainy weather that are favorable for disease outbreaks.

 

How is MilStop different from other potassium bicarbonates?

MilStop is pre-formulated with surfactants which allow it to spread over the plant easier.

 

How well does MilStop work on powdery mildew on roses in my garden?

MilStop provides excellent powdery mildew control on roses when applied at the proper frequency.

 

Will MilStop leave a residue on my flowers?

MilStop leaves little to no residue. If there is some slight residue, lowering rates and rotating with other materials can help.

 

If MilStop has a high pH and runs into my soil, will it raise the pH of my soil?

When used as the label recommends there will not be any effect on soil pH.

 BotaniGard 22WP - FAQ

How does BotaniGard 22WP work?
BotaniGard 22WP contains spores of the insect parasitic fungus - Beauveria bassiana strain GHA. After an application of BotaniGard, the spores will contact and adhere to the target insect. Within hours the spore will germinate, penetrating the cuticle (external surface or skin) of the insect. The fungus grows within the insect body, overwhelming and killing the insect. The BotaniGard 22WP spores do not infect other organisms including humans, pets, birds and other animals.

How and when do I apply BotaniGard?
Shake the bottle of BotaniGard 22WP to loosen up the powder for the most accurate measurement. Use the appropriate rate for the insect pest (see label and small volume rate sheet) and spray on the plants, covering completely so it is wet, but does not run-off. BotaniGard is most effective on the very young stages of insects. Apply at the first sign of an insect pest to control newly hatching and existing insects.

How many applications are usually necessary?
It is recommended that you make one application and follow up with a second and possibly third. The number of applications depends on the accuracy of your spray coverage, insect pressure, and environmental conditions. Applications can be made every 3 to 10 days. Heavy insect populations will require more frequent applications. Large numbers of adults or rapidly building populations may require that BotaniGard 22WP be alternated or combined with a compatible insecticide.

Have there been any plant injury issues?
Yes, but it has been rare with the 22WP formulation. Avoid spraying the BotaniGard 22WP mixture on open flowers (blooms) as they can be more sensitive than the leaves. Flower petals may burn or discolor.

Is it OK to use on my edible plants (herbs, vegetables, etc.)?
Yes. Vegetables, fruit and fresh cut herbs can be harvested the same day of application.

I saw a liquid formulation of BotaniGard (BotaniGard ES). Why do you only sell the wettable powder (22WP) on your consumer website?
Both formulations are effective. However, the dry, wettable powder formulation is easier to use and store. It can also be used on tomatoes, where the BotaniGard ES formulation cannot.

How long will my 1 pound container last when stored properly?
18 months from date of manufacture. An "expiration date" is printed on every container  and is located on the front label in the lower right corner.

Can I save leftover spray mixture that I didn't use?
No. The live spores (active ingredient) will die if left mixed in water for more than 1 day.

What's the best way to store the product?
Store in a cool, dry location (under 80o F). Keep out of reach of children.

 NemaShield - FAQ

What is NemaShield?

NemaShield is a product that consists of a large number of beneficial nematodes. These creatures are tiny round worms that attack and kill certain insect pests in the potting medium or soil.


How does it work?

After application, NemaShield nematodes actively seek out insect pest larvae or pupae. They enter the larval body, secrete a bacterium, and kill the larva within a few days. Nematodes then complete their life cycle, producing a new generation of nematodes to attack additional insect pests. NemaShield kills only larvae; it does not kill adults or eggs.

 

Is it safe?

NemaShield is a safe product. The nematodes do not affect humans. It is recommended that you follow good practices such as keeping the product out the reach of children and wash hands after using the product.

 

What does it control?

NemaShield can be used for controlling fungus gnats (larval stage only) and western flower thrips (soil borne pupal stage) in potted greenhouse crops, propagation and in interiorscape situations.

 

How is it applied?

NemaShield is applied on an area basis, so much per square feet of area. It is commonly used by commercial greenhouses in sprayers or through injector proportioning equipment. For home use, the interiorscape recommendation sheet should be followed which gives recommendations for various sized sprayers down to 1 quart. One key to successful application is the frequent agitation or stirring of the concentrated and dilute solutions. One package of NemaShield will treat a large number of pots.
