每 10kg麦种用 2 %立克秀湿拌剂 15～ 2 5g拌种 ,至第二年 4月中下旬对小麦纹枯病的病指防效仍可达 50 %左右。对枯白穗防效不同发生类型地区控病效果不同 ,相同用量的情况下 ,重发地区效果不及一般地区。每 10kg麦种用立克秀 15～ 2 5g ,重发区随着用量增加 ,效果提高。每 10kg麦种使用立克秀 2 5g ,对出苗率会产生明显影响。但重发区每 10kg麦种用 15～ 2 0 g不能达到理想的防效 ,综合考虑防效和安全性两个因素可用 2 5g ,一般发生区以用 15～ 2 0 g为宜
Per 10kg of wheat with 2% Ricker wet mixing agent 15 ~ 25g seed dressing, wheat leaf blight in late April the second half of the disease control effect is still up to 50%. On the control effect of different control types of dry white spike different regions, the same amount of circumstances, less effective resequencing areas. Every 10kg of wheat with Li Kexiu 15 ~ 25g, restart the area as the amount increased, the effect increased. The use of Li Kexiu 2 5g per 10kg of wheat germ, the emergence rate will have a significant impact. However, 15-20 g of wheat per 10 kg of wheat in the reclaimed area can not achieve the desired control effect. Considering both the control effect and the safety factor, 25 g can be used, and the average occurrence area can be 15 g to 20 g
