(Controls Sod Webworm)

Do you have moths flying when you cut your grass?

Sod webworms commonly attack Kentucky bluegrass, perennial ryegrass, fine fescue, and bentgrass maintained at a variety of mowing heights. Webworm damage starts as small yellow or brown patches in the leaf blades in lawn areas. As the caterpillars feed and grow, the patches gradually increase in size. Caterpillars are nocturnal, so you won't notice them on the surface during the day. However, if you gently pull the grass apart, you'll notice tunnels or burrows in the thatch. Often these burrows will be lined with green, pellet-like matter. This is caterpillar excrement, also known as "frass". By midsummer, large sections of a lawn might be destroyed by the sod webworm caterpillars, which prefer sunny areas. Webworm damage is particularly severe in dry conditions, partly because the grass is less able to recover from caterpillar feeding. Damage is usually most apparent in July and August, when temperatures are highest and cool season grasses are not as robust. Affected areas recover slowly from webworm feeding and often are overrun by weeds.

An application of our Guardian for Sod Webworm in late April to early May as soon as soil temperatures reach 100C (500F) and again in early July can correct this pest. NIC nematodes are isolated Canadian Strains that are reared on a live host. They are fresher, more keyed to Canadian pests and 100% organic.

10 million covers 1000 ft2 (93 m2)
25 million cover 2500 ft2(232 m2)
50 million covers 5000 ft2 (464 m2)

Note When to apply? If you have missed the spring application, the fall (September to October, as long as soil temperature are above 10C/50F) is an effective time to apply for these pests. As the temperatures drops, the sod webworm burrow into the soil to overwinter. This gives the nematodes an opportunity to control this pest.

SPECIAL NOTES: Application of 10 million nematodes should take approximately 40 minutes to apply using our hose end sprayer.
