The amount of damage caused by Meloidogyne graminis to forage grasses is currently unknown, although studies to quantify this are in progress. Log in Sign up. Diseases of woody plants fall into two major categories: infectious diseases and noninfectious diseases. Part I of the book presents the infectious pathogens and the diseases they cause. The head of Meloidogyne graminis is usually oriented toward the base of the root and the body is oriented in the opposite direction forming a cane shape (Figure 6). After traveling a short distance inside the root, they stop, and their presence causes the formation of giant cells, upon which they feed, and which form the characteristic galls. 74 4.S.DISCUSSION 89 CHAPTER S.

On other hosts, like rice and zoysia, the rear end of the mature female breaks the root surface and eggs are deposited on the root surface (Figure 11). It is of increasing concern due to the rising importance of turfgrasses in the Florida economy, the susceptibility of grasses to this nematode, and implementation of new diagnostic techniques that have brought to light the damaging potential of this nematode. Commentaries: (1) Essential oil in the leaves contains the cyclic monoterpene epoxyde 1,8-cineole and the cyclic monoterpene terpinen-4-ol (Yoon et al., 2003).Note that 1,8-cineole inhibited at the concentration of 250 µg/mL the motility of Meloidogyne incognita (Echeverrigaray, Zacaria, & Beltrão, 2010). 254), cucumber, eggplant, ginger, lettuce, potato, sweetpotato, tomato and yam), fruit crops (melon, papaya, pineapple), ornamentals, and weeds.
