Cynodon dactylon is a perennial grass that is commonly used as a laxative, expectorant, analgesic, etc. These are small herbs with shallow roots and weak stems. The rhizomes are reported to act as a diuretic in humans and the grass juice can act as an astringent. It has been observed that Cynodon dactylon may be selectively eaten by dogs to swiftly induce vomiting when they have gastrointestinal problems. It is native to most of the Eastern hemisphere and adapted for transitional climates as well. In early evolution, bacteria were phagocytosed by primitive eukaryotes for their nutrient value.

The bermudagrass pastures were stocked at three levels of forage mass to quantify cow and calf average daily gain (ADG, gain ha-1) and its relationship with mass and allowance (forage dry matter/animal body weight [DM:BW]). successfully classified Cynodon dactylon (bermudagrass) in a vineyard by combining OBIA with the decision tree (DT) algorithm. Bermuda grass, ( Cynodon dactylon ), perennial turfgrass of the family Poaceae, native to the Mediterranean region. Life Cycle: Perennial. The examples are Echinocloa colonum, Cynodon dactylon. The biomass of all dominant plant species, but not subordinate species, decreased under drought. Stubby-root nematodes are ectoparasitic nematodes, meaning that they feed on plants while their bodies remain in the soil. However, breeding efforts have significantly improved the appearance of common bermu- dagrasses. Phytoextraction in phytoremediation, in which plants uptake and transport heavy metals (HMs) to the tissues of aerial parts, is the most environmentally friendly method to reduce the total amount of HMs in soil and has wide application prospects. Mainly summer to autumn in NSW. The fall armyworm (Spodoptera frugiperda) is a species in the order Lepidoptera and is the larval life stage of a fall armyworm moth.The term "armyworm" can refer to several species, often describing the large-scale invasive behavior of the species' larval stage. Capable of disrupting the life cycle of insects at all stages (adult, larvae, and egg). Sorrel, Wood Scientific Name: Oxalis europaea. Fl.
