American burnweed, also known as fireweed, is a fast-growing summer annual broadleaf weed that colonizes disturbed ground, lawns, gardens, and roadsides across North America. It produces thousands of wind-dispersed seeds and can reach six feet tall in a single season. Because it is a broadleaf species, selective broadleaf herbicides control it without harming most grasses. … Read more

Clincher Herbicide is a post-emergent grass herbicide used to control barnyardgrass and other annual grasses in rice and other labeled crops. It contains cyhalophop-butyl, a Group 1 ACCase inhibitor that is absorbed through grass leaves and translocated to growing points. Its primary use is selective grass control in flooded and direct-seeded rice systems. Clincher is … Read more

Echinochloa crus-galli, commonly known as barnyardgrass, is one of the most widespread and competitive grass weeds in the world. It infests rice paddies, corn fields, sorghum, cotton, and vegetable crops, reducing yields by competing for water, nutrients, and light. Because it is a grass species, control requires grass-selective herbicides rather than broadleaf products. Effective barnyardgrass … Read more

Jowar, also known as sorghum, is a warm-season cereal crop grown across India, Africa, and parts of the Americas for grain, fodder, and forage. It competes poorly with weeds during the first three to four weeks after emergence, which is why early-season weed control determines final yield. Choosing the right herbicide for jowar depends on … Read more

Yellow star thistle is one of the most aggressive invasive broadleaf weeds in western North America, forming dense spiny stands that crowd out native grasses and forage on rangeland, roadsides, and pastures. It is toxic to horses and can cause irreversible neurological damage when consumed over time. Because it is a broadleaf species, selective herbicides … Read more

Purple deadnettle is a winter annual broadleaf weed that emerges in fall, overwinters as a low rosette, and blooms in early spring with small purple flowers. It spreads rapidly through seeds and thrives in thin turf, garden beds, and no-till fields. Because it is a broadleaf species, selective broadleaf herbicides control it without harming most … Read more

Green kyllinga is a warm-season perennial sedge that forms dense mats in lawns, sports fields, and golf courses across the southern United States. It spreads through underground rhizomes and produces viable seeds, and it tolerates close mowing better than most turfgrasses. Because it is a sedge, standard broadleaf herbicides do not control it. Effective green … Read more

Eurasian milfoil is a submerged aquatic weed that forms dense mats in lakes, ponds, rivers, and irrigation canals. It spreads through stem fragments that root in new areas, and it can dominate a waterbody within a few seasons. Because it grows under water, control requires aquatic-approved herbicides, not terrestrial products. Effective Eurasian milfoil control depends … Read more

Italian arum is a shade-tolerant perennial that spreads aggressively through underground tubers and berry-dispersed seeds, forming dense colonies in gardens, woodlands, and riparian areas. It is toxic to humans and pets if ingested, and its sap can cause skin irritation. Because it is a broadleaf plant, selective broadleaf herbicides control it without harming most grasses. … Read more
