THE PRODUCT

Plants that fight pests on their own.

Your plant's immune system has been waiting for this. Chitin — the molecule that makes up fungal cell walls and insect exoskeletons — is what plants evolved to detect as an incoming attack. King Krustacean delivers it directly, telling your plant to wake up its defenses before pests ever arrive.

Once chitin hits the root zone, plants ramp up chitinase production, harden cell walls, and prime systemic resistance pathways — the same mechanisms they'd deploy against a real fungal or insect attack, but proactive instead of reactive. Slow-release calcium from the same crustacean shells does the structural work: thicker walls, less BER, less tip burn.

APPLICATION

How to Use

1

Mix ¼ tbsp per gallon

Apply every 2–3 waterings during fruiting phase.

2

Soil drench at base

Calcium uptake happens in the lower root zone. Don't foliar — limited absorption.

3

Watch for tip burn

If new growth tips brown, dose up. Calcium demand spikes during fruit set.

FAQ

Product Questions

How does chitin trigger pest defense?

Chitin is the building block of fungal cell walls and insect exoskeletons. When plants detect it in the root zone, they ramp up chitinase production and prime their systemic immune response — the same pathway they'd activate against a real attack. The result: stronger natural resistance to fungal disease and insect pressure before either arrives.

Will this prevent blossom end rot?

Yes — most BER is localized calcium deficiency, not whole-plant. King Krustacean's slow-release crustacean calcium keeps supply steady through fruit set and ripening.

When during the season should I apply?

Start at transplant for the immune-priming benefit, then layer at flowering for the calcium support. Continue through harvest on fruiting plants.

How is this different from a regular cal-mag?

Synthetic cal-mag delivers calcium only — and competes with potassium and magnesium for uptake. King Krustacean delivers chitin-bound calcium that's naturally chelated (no lockout) AND triggers your plant's pest-defense pathway at the same time. Two mechanisms, one product.

Plants that fight back.

Chitin primes natural defense. Calcium hardens cell walls. Stronger crops, less spraying, fewer losses.
