笔者在天津部分区县农田看到,防治手段仍然是一家一户喷洒农药。由于喷洒药物品种不统一、药量不统一、种植作物不统一、喷洒的具体时间也不统一,造成农药虽然喷洒了不少,但防治效果不佳。在北部区县的一个乡镇,一位菜农抱怨说,他们家的菜田采取了生物农药防治以确保蔬菜农残不超标,但由于邻居家的棉田不及时防治,一夜之间害虫都爬到他家的菜田里。
I see in some districts and counties in Tianjin farmland, control measures are still a family of pesticides sprayed. Due to the non-uniform spraying of drug varieties, the dose is not uniform, crop cultivation is not uniform, spraying the specific time is not uniform, resulting in a lot of spraying pesticides, but the control effect is not good. In a township in the northern district and county, a vegetable farmer complained that his family’s vegetable fields had adopted biological pesticide control to ensure that pesticide residues in vegetables did not exceed the standard. However, pests crawled over to him overnight due to the insecurity in the neighbor’s cotton fields Home vegetable fields.
