  azoxystrobin
A similar gene expression pattern was observed after treatment with fenpropimorph and some defence-related genes were induced by azoxystrobin, demonstrating that these fungicides also activate a defence reaction.
      
Azoxystrobin, a strobilurin, inhibits fungal mitochondrial respiration and fenpropimorph, a morpholin, represses biosynthesis of ergosterol, the major sterol of fungal membranes.
      
The two fungicides azoxystrobin and fenpropimorph are used against powdery mildew and rust diseases in wheat (Triticum aestivumL).
      
Azoxystrobin and fluoxastrobin were largely ineffective in inhibiting in vitro growth of Fusarium spp.; sensitivity of the other fungi was generally lower, except for M.
      
viticola population was observed in the population sprayed with azoxystrobin, consistent with directional selection toward higher resistance, confirmed by an enhanced frequency of resistant mutants with respect to the unexposed population.

The isolates of Phytophthora infestans were collected from Inner Mongolia and Gansu province from 1997 to 2001. The mating type and chemical response of these isolates were then determined. Among 143 isolates from Inner Mongolia, 140 belonged to A1 mating type, and the other three were self fertile isolates of A1 mating type. Among 41 isolates collected from Gansu, 40 of which belonged to A1 mating type, and 1 was self fertile isolate of A1 mating type. No isolate of A2 mating type was detected. Of 120 isolates...

The isolates of Phytophthora infestans were collected from Inner Mongolia and Gansu province from 1997 to 2001. The mating type and chemical response of these isolates were then determined. Among 143 isolates from Inner Mongolia, 140 belonged to A1 mating type, and the other three were self fertile isolates of A1 mating type. Among 41 isolates collected from Gansu, 40 of which belonged to A1 mating type, and 1 was self fertile isolate of A1 mating type. No isolate of A2 mating type was detected. Of 120 isolates from Inner Mongolia were tested on the sensitivity to metalaxyl, 50.8% were highly resistant, 42.5% were intermediate resistant, and 6.7% were sensitive.For other 41 isolates from Gansu, 26.8% were highly resistant, 29.3% were intermediate resistant, and 43.9% were sensitive. Also it was found that the vegetative growth of some resistant isolates was stimulated by metalaxyl. These results showed that the resistant isolates predominated in potato major producing areas in Inner Mongolia. The sensitivity of 35 isolates to dimethomorph and azoxystrobin with different levels of metalaxyl resistance were determined, 94% of which were sensitive and 6% were intermediate sensitive to dimethomorph, while 71.4% were sensitive and 28.6% were intermediate sensitive to azoxystrobin. No isolate resistant to dimethomorph or azoxystrobin was detected, and the resistance to metalaxyl did not correlate to the resistance to dimethomorph or azoxystrobin.

1997— 2 0 0 1年在内蒙古自治区和甘肃省马铃薯主产区采集马铃薯晚疫病菌并进行了交配型和药剂敏感性测定。结果为 :采自内蒙古的 14 3株菌中有 14 0株是典型A1交配型、3株是可自育的A1交配型 ;采自甘肃的 4 1株菌中有 4 0株是典型A1交配型、1株为可自育的A1交配型 ;二省都未发现A2交配型。表明内蒙古和甘肃马铃薯主产区的晚疫病菌以A1交配型占绝对优势。对甲霜灵 (metalaxyl)的敏感性测定显示 :内蒙古菌株中有 5 0 .8%表现高度抗性、4 2 .5 %表现中度抗性、只有 6 .7%表现敏感 ,说明内蒙古马铃薯主产区的晚疫病菌普遍对甲霜灵具有了抗性 ;甘肃的菌株中 ,2 6 8%表现高度抗性、2 9.3%表现中度抗性、4 3.9%表现敏感 ;同时发现甲霜灵可刺激某些抗性菌株的生长。试验还测定了 35株菌对烯酰吗啉 (dimethomorph)和腈嘧菌脂 (azoxystrobin)的敏感性 :其中对烯酰吗啉表现敏感的占 94 %、中度敏感的占 6 % ;对腈嘧菌脂敏感的占 71.4 % ,中度敏感的占 2 8.6 % ;未发现对二种药剂高抗或不敏感菌株 ,且烯酰吗啉和腈嘧菌脂...

The control effects of preharvest azoxystrobin (AZX) treatments on downy mildews, powdery mildews and latent infection rate of fruits and pink rot, Fusarium rot on the fruits of Cucumis melo cv. Yindi, a melon variety widely planted in recent years, were investigated in the paper. The results indicated that AZX from 100 mg/L to 400 mg/L treatment reduced significantly severity of downy mildews and powdery mildews, latent infection rate of fruits, and the disease incidence of postharvest pink rot and Fusarium...

The control effects of preharvest azoxystrobin (AZX) treatments on downy mildews, powdery mildews and latent infection rate of fruits and pink rot, Fusarium rot on the fruits of Cucumis melo cv. Yindi, a melon variety widely planted in recent years, were investigated in the paper. The results indicated that AZX from 100 mg/L to 400 mg/L treatment reduced significantly severity of downy mildews and powdery mildews, latent infection rate of fruits, and the disease incidence of postharvest pink rot and Fusarium rot. The treatment at 400 mg/L of AZX showed the best control. 4 times of AZX preharvest spraying was better than 3 times. 500 mg/L of iprodione treatment could also decrease the diseases incidence; however, the effect was not as good as 400 mg/L of AZX.

研究了田间嘧菌酯处理对“银帝”甜瓜采前霜霉病、白粉病和果实真菌潜伏侵染带菌率及采后粉霉病、白霉病的控制效果。结果表明:采前喷撒100~400 mg/L嘧菌酯对甜瓜生长期间的白粉病和霜霉病均有很好的控制作用;可以明显降低果实生长发育期间潜伏侵染的真菌带菌率;还可有效降低采后常温贮藏期间粉霉病和白霉病的发病率,其中以400 mg/L处理效果最好。嘧菌酯采前处理4次的效果优于3次。对照药物500 mg/L扑海因处理也可以降低上述各类病害,但效果不及400 mg/L嘧菌酯处理。

Field control efficacy of azoxystrobin(Amistar) on cucumber downy mildew, pepper brown leaf spot, tomato early blight as well as its toxicity to their pathogenic fungi was (investigated.) The EC_(50) to Pseudoperonospora Cubensis, Collecterichum capsica, Aternaria solani are 0.004 9 μg/mL, 5.6345 0 μg/mL, 8.6176 μg/mL, respectively. Field experiments showed this fungicide was very efficacious on controlling those diseases, and their efficacies are over (80 percent.) At the same time, this fungcide was also very safe to vegetables. When sprayed at 500 μg/mL, a concentration more than two times higher than used in the field, which did not (induce) any harmful effect on vegetable development and growth.The study indicated that (azoxystrobin) be used three times successive could control those diseases,and was safety to plants.

采集未施用过甲氧基丙烯酸酯类杀菌剂地区的番茄早疫病菌Alternariasolani、辣椒炭疽病菌Collecterichumcapsica、黄瓜霜霉病菌Pseudoperonosporacubensis,于室内测定嘧菌酯对该3种病菌的毒力,结果分别为:对早疫菌的EC50值为8.6176μg/mL,对炭疽菌的EC50值为5.6345μg/mL,对霜霉菌的EC50值为0.0049μg/mL;连续两年在田间使用3个不同剂量的嘧菌酯防治上述3种病菌,均得到了80%以上的良好防效;室内盆栽番茄、辣椒、黄瓜的不同品种,于不同的生长时期,喷施不同浓度的嘧菌酯,500μg/mL浓度下未见药害。本研究表明,连续使用3次嘧菌酯即可有效控制病害的发展,而且对作物安全性高。
