番茄青枯病是南宁市郊番茄主要病害之一,每年因此病危害使生产损失很大,尤其是连年连作的番茄地损失更是严重,甚至少数田块失收,虽然实行轮作对青枯病有预防作用,但因菜地面积有限,而不可能推广,至使病区的番茄种植面积和单产都有逐步下降趋势,为此,1986年我们在南宁市郊进行药剂防治试验,经上半年探索,从中选出5种农药,在下半年进一步做防治试验.
Tomato bacterial wilt is one of the main diseases of tomato in the suburbs of Nanning. Therefore, the annual damage caused by the disease causes great loss of production. In particular, the loss of tomato in continuous cropping is even more serious, and even a few fields lose their crops. However, due to the limited area of the vegetable plot, it is impossible to popularize the tomato planting area and the yield per unit area of the ward. Therefore, in 1986, we conducted the chemical prevention and control experiment in the suburbs of Nanning. After the first half of the year, Five kinds of pesticides were selected from them and further prevention and control tests were conducted in the second half of the year.
