pioneer chemical pencycuron

Pencycuron: belongs to the Synthesis of Phenylurea Fungicide, has no translocation but has a special effect to Rhizoctonia solani. Pencycuron can be used for rice, potatoes, vegetables, ornamental plants and so on.

　We usually need to consider the amount of Pencycuron in FS about how much can achieve the result also don"t cause pollution.

　The researchers take the methods of field test, to find out the residual law of Pencycuron in cotton and soil. The results show that 100kg cotton seeds with about 75--112.5g (effective component) Pencycuron can prevention the cotton seedling diseases. Pencycuron degrades very slowly in soil, the half-life is 7.8 --10.1 d, after applying pesticide for 35 d, the degradation reaches 90%. When harvest, there is no Pencycuron in soil, cotton leaves and seeds.
