Okra [Abelmoschus esculentus L., Moench] a native of South-Africa and commonly known as ‘Bhindi’ is an annual malvaceous vegetable crop, especially grown in tropical subtropical climates. It also called “perfect villager’s vegetable”. Root-knot nematodes are considered among the top five major plant pathogens first ten most important genera parasitic world. Amongst nematodes, root-knot nematode...
Pearl millet, Pennisetum glaucum, has potential as a grain crop in the southeastern United States. Although it is used as a food grain in India and Africa, its primary use in the United States is high quality feed for poultry and livestock (1,6,15). Hybrids adapted to the southeast should be high yielding, resistant to the rust fungus Puccinia substriata var. indica, and early maturing. The two...
Pangola digitgrass (Digitaria decumbens Stent.) can be used as a pasture grass or it can be harvested as hay. I t originated in Africa and has been in t roduced to other tropical and subtropical areas of the world. Winchester and Haysl ip (5) repor ted that the grass e l iminated populat ions of the root¬ nematode, Meloidogyne incognita acrita Chitwood and Oteifa, 1952. Overman (3) sampled 7...
Dentre os biomas brasileiros, o Cerrado é segundo em extensão territorial e diversidade de espécies vegetais animais. A biodiversidade do tem sido estudada no que tange a sua flora fauna, carecendo dados microorganismos representantes da microfauna, exemplo dos nematoides galhas radiculares. Meloidogyne spp. são endoparasitas sedentários plantas. presença solo áreas com vegetação nativa cerrado...
تحقیقات پیرامون نماتدهای انگل گیاهان دارویی بطور پراکنده در کشورهای مختلف دنیا صورت گرفته است. در مطالعهای در زمینه نماتدهای انگل همراه با چند گیاه دارویی در کشور هند، شش جنس نماتد شامل Meloidogyne،Pratylenchus،Helicotylenchus، Tylenchoryhnchus، Hoplolaimus، Rotylenchus و همچنین گونه Aphelenchus avenaeبعنوان نماتدهای شایع گیاهان دارویی چون مریمگلی (Salvia officinalis)، بادرنجبویه (Melissa off...
Biotin-binding proteins (BBPs), such as avidin and streptavidin, represent potent insect control compounds which could be delivered via transgenic plants. The effects of BBPs on some pasture pests were determined. Black field cricket nymphs (Teleogryllus commodus) had significantly reduced growth and survival when fed on lettuce leaves painted with purified avidin. Adult clover root weevils (Si...
The reproductive potential of Meloidogyne graminicola was compared with that of M. incognita on Trifolium species in greenhouse studies. Twenty-five Trifolium plant introductions, cultivars, or populations representing 23 species were evaluated for nematode reproduction and root galling 45 days after inoculation with 3,000 eggs of M. graminicola or M. incognita. Root galling and egg production ...
The interactions of Meloidogyne javanica, Rotylenchulus reniformis, and Rhizobium sp. on cowpea seedlings were investigated. Upon simultaneous inoculation with the two nematode species, M. javanica invaded first but did not affect root invasion by R. reniformis. M. javanica populations increased less in competition with R. reniformis than when present alone. Preinvasion by R. renilormis signifi...
