柑桔锈壁虱是柑桔主要害虫之一。国内遍及各柑桔产区。植株被害后,叶片枯黄脱落,果实皮厚、色黑、汁酸,不仅降低了果品的价值,而且严重的影响树势。据观察,在四川柑桔锈壁虱起于初夏,7—10月盛发,在8月高温季节,繁殖迅速,猖獗成灾。应用石硫合剂波美0.1—0.3度,杀虫效果好,但不能杀卵;0.5—1.0度有杀卵作用,但容易发生药害。近年来,随着我国工业的迅速发展,杀虫、杀螨剂的新品种,均在日益增多,用来防治果树螨类已日见广泛。为了探索防治柑桔锈壁虱高效低毒的药剂,减少喷药次数,提高防治效果,特将1964—1973年在室内、外进行新农药防治柑桔锈壁虱的试验结果,整理于下,以供参考。
Citrus rust tick is one of the major citrus pests. Domestic citrus producing areas throughout. Plant damage, the leaves fall off yellow, thick fruit, dark black, sour, not only reduces the value of fruit, but also seriously affect the tree potential. It is observed that citrus rust ticks in Sichuan begin in early summer and flourish in July-October. In the hot season of August, the breeding rapid and rampant catastrophe. Application Baume sulfur Baume 0.1-0.3 degrees, insecticidal effect, but can not kill eggs; 0.5-1.0 degrees have ovulation, but prone to injury. In recent years, with the rapid development of our country’s industry, new varieties of insecticides and acaricides have been increasing day by day. It has been widely used to control fruit tree mites. In order to explore efficient and low toxicity of citrus rust tick agents, reduce the number of spraying and improve the control effect, especially in 1964-1973 indoors and outside the new pesticide citrus rust tick control test results, sorted out, for reference.
