水稻纹枯病、纵卷叶螟、螟虫(二化螟、三化螟)系我县水稻上的主要病虫害。常年发生面广,危害损失严重。以往,农户在防治上采取井岗霉素、杀虫单(双)或甲胺磷等单剂或药剂混配兼治病虫。近年来,为简化农户混配使用手续,提高混配科学性、合理性、实用性,已研制并生产出农药混剂“纹螟丹”防治水稻病虫。该药剂系井岗霉素与杀虫单复配制剂。我们于1992年对其进行了田间药效试验,并根据本地稻区病虫发生特点,提出应用对策及注意事项如下,以便农户能掌握一药多治技术,提高对病虫综防技术水平。
Rice sheath blight, leaf roller, stem borer (Sesamia inferens, rice stem borer) Department of rice in my county the main pests and diseases. A wide range of perennial, endanger the loss of serious.

In recent years, in order to simplify the procedures of farmers to mix and use, improve the scientific, rationality and practicability of blending, we have developed and produced pesticide mixture “Carteretans” to prevent and control rice pests and diseases. The drug is Jinggangmycin and insecticide single complex preparation. In 1992, we conducted a field trial of its efficacy. Based on the characteristics of pests in the local rice-planting areas, we put forward application countermeasures and precautions as follows, so that farmers can master multiple drug treatment technologies and improve their pest and disease control technologies.
