The story of Pvent begins back in 1989 when the active ingredient, Gliocladium catenulatum Strain J1446, was first isolated from field soil in Finland. They were initially looking for a solution for Fusarium culmorum in wheat, but soon discovered that their unique strain was capable of much more. It not only proved to be effective against several plant and root pathogens and some foliar diseases, it also showed biostimulating properties that improved plant growth and health. It took a decade to bring Pvent to market and now it is registered in 18 countries.
All the hard work and expertise put into it paid off with Pvent; it is highly effective for a wide range of crops in nearly any growing environment and its ease of use and multiple modes of action make it an excellent choice for any IPM (Integrated Pest Management) program.
Pvent is a wettable granule (WG) that:
- Controls pathogens in three ways: it will attack, destroy and defend against them.
- Provides an enzyme secreted by G. catenulatum, which ruthlessly attacks only pathogenic fungi.
- Rapidly colonizes its host environment and immediately begins working symbiotically in the plant rhizopheres, root zone and in all new growth.
- Provides 3 to 4 weeks of highly populated protection.
- Feeds on fungi on treated surface and then reproduces on the same area to ensure against pathogenic re-infection.
- Promotes Induced Systemic Resistance (ISR) properties in existing plants.
- Can be mixed and applied through multiple practices such as: nurse tank, direct chemigation, spot drench, directed spray treatments, foliar sprays, overhead chemigation, soil drench or fogging.
- Can be used in conjunction with other bactericides/fungicides
- Has a zero-day Pre-harvest Interval (PHI=0 days)
For use as a biofungicide to control soil and foliar pathogens in crops growing in a wide range of media and environments. Pvent is a preventative fungicide. For best results, apply early as possible in the season and continue to apply often.
This Product Controls These Pests or Diseases:
- Seed-borne and soil-borne plant diseases such as damping-off, root and stem rot.
- Wilt caused by Alternaria, Bipolaris, Botrytis, Cladosporium, Colletotrichum, Fusarium, Mycosphaerella, Penicillium, Phytophthora, Plasmodiophora, Plicaria, Pyrenochaeta, Pythium, Rhizoctonia, Sclerotinia and Verticillium.
- Certain storage diseases caused by Helminthosporium and Rhizoctonia.
- Foliar diseases like grapevine trunk diseases (several pathogens).
- Diseases caused by Alternaria, Anthracnose (Colletotrichum), Bipolaris, Botrytis, Cladosporium, Didymella, Fusarium, Monilinia, Mycosphaerella, Penicillium and Sclerotinia.
- Also suppresses powdery mildew symptoms on greenhouse or field-grown crops.
Apply Pvent by spraying or drenching the growth substrate, by incorporation into the growth substrate, as a foliar spray, by fogging or by hydroponic or chemigation application in the field or greenhouse as an aqueous suspension. For detailed application instructions per application methods, please refer to the manufacturer's label under the DOCS tab.
- Foliar Spray – 0.33 oz. per 5 gallons of water. Repeat applications every 7-14 days, depending on disease pressure.
- Greenhouse or Nursery Soil/Media Drench – 0.33 oz. PVent per 2.5 gallons of water (0.1% suspension). Repeat applications every 3 weeks depending on disease pressure.
- In-Furrow – 0.45-0.90 lbs. PVent per acre. Apply in 5-25 gallons of water per acre as a directed spray into the seed furrow just before seeds are covered. Use high rate for high disease pressure and/or high plant density.
- Additional application methods and rates are listed on the Product Label.
Preparing an aqueous suspension of Pvent - To prepare an aqueous suspension of PVent, mix product in a small volume of water such as 1/2 gallon (e.g., 0.35 oz. of PVent per 1/2 gallon of water). For best results, let the suspension stand 30 minutes. Agitate sufficiently to evenly disperse product before diluting to final volume. Apply the aqueous suspension as a dip, drench or spray or via drip or sprinkler chemigation or incorporation in potting media. Use the aqueous suspension within 1 day of preparation. For examples of mixing ratios, please refer to page 8 of the manufacturer's label under the DOCS tab.
PVent has been evaluated for phytotoxicity on a variety of crops under various normal growing conditions. However, testing all crop varieties in all mixtures and combinations is not feasible. Prior to treating entire crop, test a small portion of the crop for sensitivity.
Do not combine Pvent in the spray tank with other pesticides, surfactants, adjuvants or fertilizers if there has been no previous experience or use of the combination to show it is physically compatible, effective and non-injurious under your use conditions. Observe the most restrictive of the labeling limitations and precautions of all products used in mixtures.
Environment: Can be applied to crops in field, covered for field and covered production (i.e., nurseries, greenhouses).
Cannot Be Shipped To: AK,AL,CA,HI,KS,MD,MI,MN,MS,NE,PA,PR,SD,TN,WI
Warning & Toxicities: HAZARDS TO HUMANS AND DOMESTIC ANIMALS - CAUTION: Harmful if swallowed or absorbed through skin. Avoid contact with skin, eyes, or clothing.
