systemic insecticide वाक्य

Purdey, who has observed neurological disorders suffered by British farmers who used OPs, has repeatedly pointed the finger at phosmet, a systemic insecticide which farmers like him were ordered to use by the Ministry of Agriculture, Fisheries and Food ( MAFF ) on their dairy herds.
In a series of papers it concludes that these systemic insecticides pose a serious risk of harm to a broad range of non-target invertebrate taxa often below the expected environmental concentrations and that their present scale use not a sustainable pest management approach and compromises the actions of numerous stakeholders in maintaining and supporting biodiversity and subsequently the ecological functions and services the diverse organisms perform.
