摘要:

为了筛选对小麦条锈病具有较好防效的杀菌剂,为新疆小麦条锈病的科学防治提供依据。通过田间药效试验,采用随机区组的方法,定点调查各处理小麦条锈病发生情况,评价供试药剂对小麦条锈病的防治效果。结果表明,240 g/L氯氟醚·吡唑酯SC、19%啶氧·丙环唑SC、23%醚菌·氟环唑SC和75%肟菌·戊唑醇WG对小麦条锈病的防治效果较好,防效最高达到82.64%、77.28%、71.36%和70.93%。40%腈菌唑WP、42%苯菌酮SC、430 g/L戊唑醇SC、43%氟嘧·戊唑醇SC和48%苯甲·嘧菌酯SC对小麦条锈病的防效为61.11%~64.89%。建议在生产上推广240 g/L氯氟醚·吡唑酯SC、19%啶氧·丙环唑SC、23%醚菌·氟环唑SC、75%肟菌·戊唑醇WG、40%腈菌唑WP、42%苯菌酮SC、430 g/L戊唑醇SC、43%氟嘧·戊唑醇SC和48%苯甲·嘧菌酯SC的轮换使用,有效控制小麦条锈病危害,提高粮食生产安全。

Abstract:

To screen the fungicides with good control effect on wheat stripe rust (Puccinia striiformis West. f. sp. tritici Eriks ET Henn), and to provide a basis for scientific control of wheat stripe rust in Xinjiang, a field efficacy test was carried out by randomized block method. The occurrence of wheat stripe rust in the wheat field was investigated at the designated site, and the control effects of fungicides on wheat stripe rust were evaluated. The results show that 240 g/L Mefentrifluconazole·pyraclostrobin SC, 19% Picoxystrobin·propiconazole SC, 23% Epoxiconazole·kresoxim-methyl SC and 75% Trifloxystrobin·tebuconazole WG are effective in the control of wheat stripe rust, and the highest control effect of these four agents is 82.64%, 77.28%, 71.36% and 70.93%, respectively. The control effect of 40% Myclobutanil WP, 42% Metrafenone SC, 430 g/L Tebuconazole SC, 43% Fluoxastrobin·tebuconazole SC and 48% Difenoconazole·azoxystrobin SC on wheat stripe rust is from 61.11% to 64.89%. It is suggested that 240 g/L Mefentrifluconazole·pyraclostrobin SC, 19% Picoxystrobin·propiconazole SC, 23% Epoxiconazole·kresoxim-methyl SC, 75% Trifloxystrobin·tebuconazole WG, 40% Myclobutanil WP, 42% Metrafenone SC, 430 g/L Tebuconazole SC, 43% Fluoxastrobin·tebuconazole SC and 48% Difenoconazole·azoxystrobin SC should be used alternately to control wheat stripe rust, which could have good control effect and improve the food production safety.

Key words: desert and oasis wheat region, fungicide, Puccinia striiformis f. sp. tritici, control effect, food production safety
