Aim:Getting safe, reliable, cost-effective control of Lepidoptera pests in a full spectrum of horticulture crops (including conventional and organic production).


Introduction:DiPel is the number one biological insecticide in the world. This potent Bacillus thuringiensis (Bt) insecticide provides proven control of Lepidoptera pests in many crops. Its balanced blend of four active toxins, plus a natural spore, provides exceptional control. This varied list of active toxins also makes DiPel an effective resistance management tool.

DiPel can be applied in conventional or organic systems. Because it is Exempt from Tolerance, DiPel gives grower’s full confidence when selling crops to foreign markets. In addition, DiPel’s superior, high-potency, dry-flowable formulation ensures the longest shelf life of any other Bt on the market.

Other Benefits of using DiPel: The safety and environmental profile of DiPel insectide results in no re-entry intervals and the shortest pre-harvest intervals (PHI) allowed by law. This gives growers great flexibility throughout the growing season.

In addition, DiPel is exempt from tolerance, which means growers don’t need to worry about selling into export markets due to residue issues.

DiPel is OMRI-certified for use in organic production. It provides organic growers with a proven and highly effective natural tool to fight insect pests.


Mode of Action: DiPel is created with a naturally occurring bacterium found in soil and on plant leaves throughout most regions of the world. It contains insecticidal proteins and spores that become active inside the insect’s gut when ingested by Lepidopteran larvae.

The most potent Bt products deliver multiple modes of action in the insect’s gut, which make it a valuable tool in resistance management. In fact, many new insecticide technologies are being met with resistance – emphasizing the need for Bt insecticides.

BeingthestrongestBtproductonthemarketDiPelgoestoworkquickly.Onceingested, the Bt toxins bind to the midgut cells, creating performances in the gut lining and causing the insect to stop feeding within several minutes. Bt spores then penetrate the body cavity and circulatory systems. The spores germinate, spread through the body and cause poisoning. Insects start to die one to three days after ingestion.

While lethal to Lepidopteran pests, studies have shown that DiPel does not harm humans, the environment or beneficial insects that are pests’ natural predators.

1. The Bt toxin crystals dissolve in the midgut.

2. The Bt toxins are activated and attach to midgut receptors.

3. Pores form in the cell wall and cells rupture.

4. Bt spores will invade the insect body, death follows.

Application Rate and Timing:Apply DiPel when insects pests are small (early instars) before crop damage has occurred. DiPel should be applied to actively growing larvae. The pest will stop feedingimmediatelyanddiewithin1-3days.Repeatatanintervalsufficienttomaintaincontrol,usually3-14daysdependingonplantgrowthrateand population density, rainfall after treating and other factors.

The best application timing is at egg hatch of the target pests, from petal fall through to green fruit stage. Weekly applications may be necessary if egg hatch is asynchronous. Also, DiPel application is similar to all common insecticides: best applied in the evening or in overcast conditions.

Good coverage is essential to ensure the crop is well protected. Apply in sufficient water volume to cover all foliage and fruit surfaces. A spreader-stick which has been approved for use on growing and harvesting crops should be added to “hard to wet” crops such as cabbage, or to improve weather fastness of the spray deposits.

The best time to apply is when the larvae are young. After eating a lethal dose of DiPel, the pest will stop feeding immediately and die within 1-3 days. Mortality varies with with larval size, lepidopteran species and dose consumed. In heavy pest pressure, higher rates of DiPel are recommended.

The Program:Early season: Apply DiPel alone at bloom or add it to a tank-mix to improve insect control . You can also use DiPel as an economical alternative to other soft insecticides to preserve beneficial insects and to avoid flaring secondary insects.

Mid-Season:Maximizeduringthemiddle.UseDiPelmid-seasontoimproveperformance and reduce the risk of resistance due to DiPel’s multiple modes of actions.
