Services
Fungicides
Our fungicides provide effective disease control for conventional and organic crops. Formulated with potassium-enhanced lime sulfur, these products combat fungal infections while improving plant health. No harmful effects on pollinators make them ideal for integrated pest management systems.
Rodenticides
We offer a comprehensive line of rodenticides with multiple active ingredients and bait formulations. Our solutions address agricultural pest problems from small-scale infestations to large biosecurity programs. Products feature food-grade ingredients for maximum bait acceptance.
Solar Protectants
Patented solar protectants convert infrared light to visible spectrum, enhancing photosynthesis while preventing sunburn. These formulations improve water efficiency and plant health without blocking beneficial light wavelengths essential for crop development.
Chilling Products
Our calcium carbonate formulations optimize chilling hours for fruit and nut crops. By delaying bud break and improving carbohydrate storage, these products enhance bloom uniformity and increase yield potential in temperate climate crops.
Slug Baits
We manufacture proven slug and snail baits with dual-action chemistry. Our formulations combine metaldehyde and sulfur for contact and ingestion control, featuring visible pellets that ensure even application and effective pest population management.
