乌克兰采购需求：激动剂，噻虫嗪，三环烯，杀虫剂

I represent a leading Ukrainian agricultural holding company, specializing in the production of animal feed and related products. We're currently looking into purchasing a specific insecticide that targets houseflies. To proceed effectively, we would like to request a sample of the product to evaluate its suitability for our needs. Additionally, please provide pricing details for an order of 500 kg, along with the DAP Poltava terms. Any information on lead times and shipping would also be appreciated. We are keen to establish a potential partnership, so timely responses would be beneficial.
