2. Puncture Vine Tribulus terrestris - AKA Goats Head, Devil Horns, etc. Puncture vine is a prostrate, mat-forming summer annual. It has small leaflets and small yellow flowers with 5 petals. It is also toxic to sheep.A typical puncturevine plant will produce 200 to 5,000 seeds during one growing season, depending on available soil moisture and other environmental factors. These seeds and those that did not germinate from previous seasons will contribute to the potential weed population the following year. www.arbico-organics.com/product/puncturevine-weevil-Microlarinus-lareynii-Microlarinus-lypriformis/puncturevine-goathead-texas-sandbur-controlPuncturevine Weevils control Puncturevine weeds (Tribulus terrestris), which are also known as Goatheads, Texas Sandburs, or Jamaica Feverplants. Puncturevine weevils are only available July 1 to approximately September 30th each year. Order the weevils and release as soon as green seed burs have formed. Be Patient! It may take up to 2 years to reduce the puncturevine weed numbers in your fields. Once established, the weevils will control the puncturevine - a few old seeds may sprout and grow, but the new plants will not make viable seeds nor will the plants spread as rapidly. ag.colorado.gov/conservation/biocontrol/puncturevine

3. Buffalo Buren.wikipedia.org/wiki/Solanum_rostratumSolanum rostratum is a species of nightshade (genus Solanum) that is native to the United States and northern and central Mexico.[1] Common names include buffalobur nightshade,[2] buffalo-bur,[3] spiny nightshade, Colorado bur, Kansas thistle, bad woman, Mexican thistle, and Texas thistle. It is an annual, self-compatible herb that forms a tumbleweed.[4] Individual plants reach 1–1.5 m (3.3–4.9 ft) tall, have once or twice pinnatified leaves (see image of leaf), and abundant spines on the stems and leaves. It produces yellow flowers with pentagonal corollas 2–3.5 cm (0.79–1.38 in) in diameter and weakly bilaterally symmetric (see flower-closeup image).[5] In its native range S. rostratum is pollinated by medium- to large-sized bees including bumblebees.[6] Solanum rostratum flowers exhibit heteranthery, i.e. they bear two sets of anthers of unequal size, possibly distinct colouration, and divergence in ecological function between pollination and feeding.[7] The fruit, a berry, is enclosed by a prickly calyx. The seeds are released when the berries dry and dehisce (split apart) while still attached to the plant.

7. Purple Mustard - Blue Mustard en.wikipedia.org/wiki/Chorispora_tenellaChorispora tenella Blue mustard is a winter annual that germinates in the fall and produces a rosette with deeply lobed leaves, similar in appearance to a dandelion. Blue mustard bears purple or blue flowers at the top of the plant in March through April. Leaves on the flowering stems are coarsely toothed and have wavy margins. The plant may grow from 1 to 1 1/2 feet in height. Two-inch long, bean-like seedpods (siliques) that resemble "beaks" mature in early summer.
