Fallopia japonica typical to see much smaller plants in places where they sprout through cracks in the pavement or are repeatedly cut down. The leaves are broad oval with a truncated base, long and broad, with an entire margin. The flowers are small, cream or white, produced in erect racemes long in late summer and early autumn. Closely related species include giant knotweed ("Fallopia sachalinensis", syn. "Polygonum sachalinense") and Russian vine ("Fallopia baldschuanica", "Polygonum baldschuanicum"). Other English names for Japanese knotweed include fleeceflower, Himalayan fleece vine, monkeyweed, monkey fungus, Hancock's curse, elephant ears, pea shooters, donkey rhubarb (although it is not a
Nematophagous fungus already done so. The hypha then pierces the egg and devours the developing juvenile nematode before producing conidiophores and growing on towards nearby eggs. Some species of nematophagous fungi are being investigated for use in biological pest control. "Purpureocillium lilacinum", for example, infests the plant-parasitic "Meloidogyne incognita", which attacks the roots of many cultivated plants. Trials have provided varying results, with some strains being aggressive and others less pathogenic, and some strains that appeared promising in the lab proved ineffective in the field. "Arthrobotrys dactyloides" shows promise at controlling the cosmopolitan plant-parasitic root-knot nematode "Meloidogyne javanica". Nematophagous fungus Nematophagous fungi
