Excerpts from:  Southwest Desert Flora; Tribulus terrestris, Puncturevine

IDENTIFICATION

Puncturevine grows up to 10 inches or so and is a low-growing prostrate species.  Its stems range from silky to hairy and it has green compound leaves with 6 to 12 leaflets.  It also produces yellow flowers, breaking up into 5-nutlets with strong dorsal spines.

IMPACT

In North America, Tribulus terrestris is considered weedy or invasive by 46 states.

Tribulus terrestris is a weedy herb introduced from southern Europe and expanding its range throughout most of North America. Tribulus terrestris is aptly called "Puncture Vine" because its fruits easily puncture bicycle tires and ready inflict pain on unsuspecting humans and perhaps small mammals as well.

CHEMICAL CONTROL

Pre-emergent herbicides can help prevent puncturevine outbreaks if you apply before or during the growing season, which is March to October.

Excerpts from:  Spotted Spurge and other Spurges

IDENTIFICATION

Spotted spurge grows close to the ground, often forming a dense mat. Its dark green leaves, which grow in pairs called “opposites,” are 1/8 to 1/2 inch long and about 1/8 inch wide.  Frequently a red spot will mark the leaf halfway down its center vein.

IMPACT

Spotted spurge can establish itself in horticultural, agricultural, and non-crop sites. It overgrows sparse turf areas and low-growing ground covers, invades open areas in gardens and landscapes, and can grow in sidewalk cracks. In addition to reducing the growth of desirable plants, spotted spurge reduces uniformity and quality of turf, provides a habitat for undesirable insects in citrus groves, serves as an intermediate host for fungal diseases of cultivated crops, and attracts ants with its seed.

CHEMICAL CONTROL

Pre-emergent herbicides can help prevent spotted spurge outbreaks if you apply them in late winter before weed seeds germinate. Time the application, so it occurs before the soil temperature exceeds 55° to 60°F at a depth of 1 inch.
