in the course of the present study, samples were taken from the non-defoliant strain of verticillium dahliae (ss-4) from infected olive groves in toshan area in southern gorgan. root-knot nematode, meloidogyne javanica, was recovered from infested olive seedlings and after identification was reaned on tomato seedlings cv. rutgers. during the study, one-year-old seedlings of olive cultivars zard...

Sweet potato is the seventh-ranked food crop produced after wheat, rice, maize, potato, barley, and cassava in world. It most important root tuber temperate, subtropical, tropical areas of grown for food, income-generating, jobs farmers retailers. The nutritional substances sweet potatoes are ß-carotene anthocyanins. However, production its valuable products limited due to root-knot nematode pa...

The response of 29 rye, oat, triticale, and wheat cultivars to selected nematode species was determined in the greenhouse. Variability in nematode root galling and final nematode population densities in root and soil in response to cool season annual graminaceous crops occurred for spiral (Helicotylenchus dihystera), stubby root (Paratrichodorus minor), and root-knot (Meloidogyne incognita) nem...

Meloidogyne incognita, the root-knot nematode (RKN), a devastating plant parasitic nematode, causes considerable damage to agricultural crops worldwide. As sedentary root parasite, it alters root’s physiology and influences host’s phytohormonal signaling evade defense. The sustainable management of RKN remains challenging task. Hence, we made an attempt investigate nematicide activity Bacillus ...

Twelve soil drenches over a period of 30 days with DBCP concentrations of 40 microg/ml did not completely prevent infection of tomato plants by root-knot nematode juveniles. Repeated DBCP drenches of 40 microg/ml halted gall development during the drenches, but 10 days after drenching was discontinued galls were apparent. DBCP drenches at 200 microg/ml prevented tomato root development, and 40 ...

The cotton root-knot nematode, Meloidogyne incognita acrita, reproduced on the roots of grain sorghum, causing syncytia in the cortex or stele of lateral roots. Giant cells developed either singly with few nuclei or in groups with many nuclei. Giant cells that developed in groups appeared the same as those which developed singly. The pericycle and endodermis were interrupted at the site of nema...
