Which substance is allowed for pest control?

Lime sulfur is a substance allowed for pest control due to its properties as a fungicide and insecticide, particularly in organic farming. It is a mixture of calcium polysulfides, which makes it effective against a range of pests and diseases while being safer for the environment when compared to many synthetic chemicals.

Lime sulfur is often used in horticulture and agriculture to manage diseases like powdery mildew and to control various insects. Its acceptance in pest control is based on its relative effectiveness and lower toxicity to non-target organisms, especially when used according to recommended guidelines.

In contrast, the other substances listed are generally restricted or banned due to their toxicity and potential negative impacts on human health and the environment.
