| چکیده نماتد مولد غده (Meloidogyne spp.) با 105 گونه شناخته شده و دامنه میزبانی وسیع، خسارت زاترین نماتد بیماریزای گیاهی محسوب می گردد. در مطالعه حاضر، میزان اثربخشی گوگرد آلی و گونه های قارچی Trichoderma afroharzianum، T. crassum و دو جدایه از T. harzianum بر تفریخ تخم و مرگ و میر لارو سن دو نماتد Meloidogyne javanica در بازه های زمانی مختلف و در قالب طرح پایه کاملاً تصادفی با پنج تکرار در شرایط آزمایشگاه مورد بررسی قرار گرفت. اثر عصاره ی قارچ ها در سه سطح پایه ،0/1 و 0/01 در دو آزمایش مجزا بر روی مرگ و میر لارو سن دو نماتد پس از 24، 48 و 72 ساعت و نیز تفریخ تخم پس از 2، 4، 6 و 8 روز مورد بررسی قرار گرفتند. نتایج بررسی ها نشان داد مؤثرترین تیمار، گونه T. carssum می باشد که در غلظت پایه و زمان 72 ساعت موجب مرگ و میر لارو سن دو M. javanica به میزان 83/3 درصد و در غلظت پایه و زمان هشت روز باعث جلوگیری از تفریخ تخم ها به میزان 63/1 درصد گردید. . | ||

| Root–knot nematode (Meloidogyne sp.) with 105 known species and a wide host range is considered the most damaging plant parasitic nematode. Doing esearch on the control of this nematode without using of chemical pesticides is necessary in order to preserve the environment. The interaction effect of Meloidogyne javanica, sulfur and Trichoderma afroharzianum, T. crassum and two isolates of T. harzianum was investigated in a completely randomized basic design with five replications under laboratory conditions. The effect of fungal extracts at three levels of concentration (basic, 0.1 and 0.01) were investigated in two separate experiments on second stage larval mortality of the nematode at 24, 48 and 72 hours as well as egg hatching after 2, 4, 6 and 8 days. The results of the studies showed that after 72 hours, T. carssum at the basic concentration level had the greatest effect on the mortality of second stage larvae of M. javanica, with a rate of 83.3%. Also, it was showed that T. crassum at the basic level of concentration had the highest effect on inhibiting egg hatching after eight days with a rate of 63.1%. | ||
