Per-Cal Mix combines the quick knockdown effect of Phytoseiulus persimilius with the longer staying power of Amblyseius californicus for greater spider mite control.
Rate: one blister will cover approximately 250 sq. ft. or loose release .05 to 2 mites/ sq. ft.
Phytoseiulus persimilis is a tropical predatory mite that moves rapidly and feeds on two-spotted mite eggs, nymphs, and adults. This aggressive, tropical predator needs fairly warm conditions to survive. Optimum conditions are 68-81°F, the predators reproduce faster than spider mites.
Amblyseius californicus is a very versatile predatory mite, tolerating a wider range of temperatures and lower humidity than P. persimilis. Californicus are well adapted to high temperatures up to 90°F as long as relative humidity is over 65%. It does best in warm, humid conditions, but will also tolerate low humidity (40% – 80% RH at 50°-105°F). These beneficial mites feed on pollen and spider mites and survive well even when pest populations are low if there is a pollen source. They can move easily through spider mite webbing.
Organic pest control, safe for plants, people and pets.
