In this paper, the pathogens of pea root rot from Dinxi, Tongwei counties were studied with different isolating media such as PDA, WA, carrot bait, water culture. Two hundred and thirty five isolates were obtained from 1734 pieces of 820 plants of diseased peas. After purification, pathogenic test, reisolation and identification, the 235 isolates belong to seventeen species of 11 genera. According to the identification results of isolating rate and pathogenicity, Fusarium solani(Mart.)Sacc, Aphanomyces euteiches,...

In this paper, the pathogens of pea root rot from Dinxi, Tongwei counties were studied with different isolating media such as PDA, WA, carrot bait, water culture. Two hundred and thirty five isolates were obtained from 1734 pieces of 820 plants of diseased peas. After purification, pathogenic test, reisolation and identification, the 235 isolates belong to seventeen species of 11 genera. According to the identification results of isolating rate and pathogenicity, Fusarium solani(Mart.)Sacc, Aphanomyces euteiches, Thielaviopsis basicola, Gliocladium catenulatum Gilman et Abbott Rhizoctonia solani Kuhn, Fusarium oxysporum Schlecht, Pythium spp. and Ascochyta spp. are main components of pea root rot complex. In addition to Fusarium solani, Fusarium oxysporum and Aphanomyces euteiches, the rest of them that have pathogenicity on peas are new records in China.

在豌豆根腐病病原研究中,采用了PDA、WA组织分离、胡萝卜诱饵分离及水培养分离等不同的分离技术,共分离病株820株,病组织1734块,获得菌株235个,经初步鉴定确定为17个不同的种,对这些分离物采用灭菌土盆栽、蛭石盆栽、纸卷法、断根法等接种技术进行致病性测定。根据分离率和致病性测定结果,认为发生在甘肃中部地区的豌豆根腐病是由茄镰刀菌(Fusarium solani(Mars)Sacc)、豌豆丝囊霉(Aphanomyces euteiches)、链孢粘帚霉(Gliocladium catenulatum Gilman et Abbott)、尖孢镰刀菌(Fusarium oxysporum Schlecht)、根串珠霉(Thielaviopsis basicola)、立枯丝核菌(Rhizoctonia solani Kuhn)、腐霉(Pythium spp)和壳二孢菌(Ascochyta spp)等复合侵染引起的。根据文献记载,上述各类菌除茄镰刀菌、尖孢镰刀菌和丝囊霉之外,其余真菌在豌豆上的致病性国内未见报道,链孢粘帚霉作为豌豆根腐病的致病菌为国内外首次报道。

The root rot of pea (Pisum sativum L.)is a new disease in the central dry region of Qinghai province. In recent years, this disease has been rapidly dispersed throughout the region. Thg plants of pea were injured seriously by this dissase and the yield was highly reduced.According to ths identification results of isolating rate and pathogenicity, Fusarium solani(Mart)Sacc. Fusarium oxysporum Scblecht, Aphanomyces euteiches Drechs, Rhizoctonia solani Kuhn, Thielaviopsis basicola (Cerk & Br.)Ferr. Pythiumum ultimum...

Pythiumum ultimum Trod,Gliocladium catenulatum Gilmant et Abbott Papulospora spp. are main components of pea root rot complex. The results of inoculation and re-inoculation experiments,bowever, proyed that the Fusarium had a higher virulence than the others, and the Pythium had an action for increasing the degree of rot.It is suggested that the Fusarium is a main pathogen for root rot of pea. So far, the main species of Fusarium isolation from the root rot plants of pea are Fusarium oxysporum and F. solani.

豌豆极腐病是青海东部干旱地区豌豆生产上的一种新病害,近年来危害逐年加重,致使豌豆产量遭受严重损失。根据分离鉴定和致病性测定结果,青海豌豆根腐病病原真菌是由茄镰刀菌、尖孢镰刀菌、豌豆丝囊霉、根串珠霉、立枯丝核菌、腐霉、链孢粘帚霉等复合反染所引起的。经回接试验:镰刀菌和豌豆丝囊霉对豌豆具有较强的致病力;腐霉及其他病原菌则有加强腐烂作用。

The experiments of an integrated control of root rot complex of Panax notoginseng in continuous cropping were carried out in Wenshan,Yunnan during 2002~2004 by means of soil fumigation and treatments to seeds,seedlings and their rhizosphere soil with Bacillus subtilis strain G3 dust and fungicide mixture.The results were as follows.1) Fumigating soil with 30~40 g/m~2 98% Dazomet,40~60 g/m~2 35% K-Vapam or 30~90 g/m~2 CaCN_2 reduced weeds,fungi,bacteria and nematodes by 90%~99% and significantly improved...

The experiments of an integrated control of root rot complex of Panax notoginseng in continuous cropping were carried out in Wenshan,Yunnan during 2002~2004 by means of soil fumigation and treatments to seeds,seedlings and their rhizosphere soil with Bacillus subtilis strain G3 dust and fungicide mixture.The results were as follows.1) Fumigating soil with 30~40 g/m~2 98% Dazomet,40~60 g/m~2 35% K-Vapam or 30~90 g/m~2 CaCN_2 reduced weeds,fungi,bacteria and nematodes by 90%~99% and significantly improved the percentage of establishment of oneand two-year-old P.notoginseng seedlings,and the incidence of root rot complex significantly decreased in the first three months of growing season.Dazomet had the best effect among the three fumigants.2) After soil fumigation,for pre-sowing treatment to the seeds and pre-transplanting treatment to the roots,the G3 dust combined with Ronilan WP had a better control efficacy than the G3 dust combined with Thiabendazol WP or Iprodione WP.The control efficacy of applying mixture of G3 and chemical fungicides after soil fumigation was significantly higher than that of an only soil fumigation.Appling only G3(2×10~(10) cfu/g at dose of 3 kg/100 m~2) to soil below 15 ℃ had not an obvious control effect.3) Soil fumigation +G3 +mixture of chemical fungicides had the best control efficacy in the experiments.

以土壤熏蒸剂、枯草芽孢杆菌、选择性杀菌剂复配剂处理种苗和根围土壤为主要方法,对连作田三七根腐病复合症进行了综合治理试验。结果表明:(1)大扫灭(98%含量,30~40 g/m2剂量)、钾-威百(35%含量,40~60 g/m2剂量)和氰氨化钙(60~90 g/m2剂量)对三七连茬病土进行熏蒸处理后,真菌、杂草、细菌和线虫灭生效果达90%~99%,1年生与2年生三七成苗率显著提高,生长季前期3个月内根腐病复合症发病率明显降低,其中大扫灭灭生效果突出。(2)土壤熏蒸后,用G3菌剂(枯草芽孢杆菌)与单杀菌剂农利灵、噻菌灵和扑海因组合播前拌种和移苗前沾根处理,其中以菌剂与农利灵组合最好,噻菌灵和扑海因组合次之。枯草芽孢杆菌G3菌剂(2×1010/cfu/g用量3 kg/100 m2)单独施用,在田间温度低于15℃条件下无明显防效。(3)熏蒸+G3+化学杀菌剂复配剂1或2播种前拌种和移栽前沾根处理组合试验防效最好。
