Chlorpyrifos, an emulsifiable pesticide, is moderately toxic. It is a cholinesterase inhibitor that has contact, stomach, and fumigation effects on pests. Mainly used to control cotton bollworm.
The drug was started at the age of the young nymphs of cotton bollworm. The safe interval for cotton was 21 days, and the maximum dose was 3 times per season. It can not be mixed with alkaline pesticides. This product is toxic to aquatic organisms such as fish, bees and silkworms. During the application period, it should avoid the influence on the surrounding bee colony, the flowering period of honey source crops, the vicinity of silkworm and mulberry gardens. Corrosive to brass. Tobacco, lettuce, melon seedlings, azaleas, camellia, and roses are sensitive to this product.
A granular preparation processed from an auxiliary agent such as a crude drug or a carrier. The earliest field trials of granules began in 1946, and were widely used in the United States in the early 1950s. In the early 1960s, Japan began to use it in large quantities.
In the late 1960s, due to the development of environmental science, GR were widely used in the world to avoid contamination of the environment and crops by particle drift during pesticide powder spreading. The development of granules in China was mainly in the late 1970s. In 1989, the MOCI statistic granules accounted for about 7% of the entire pesticide formulation. GR can be a commonly used pesticide formulation because of its many unparalleled strong points. The characteristics of granules are as following: it is directed against target insects when applied, so that the spreading agent can fully reach the target pests and no harm to beneficial organisms such as natural enemies; the drug particles do not adhere to the stems and leaves of the plant, to avoid direct contact with phytotoxicity; no dust is flying during application, and this formulation does not pollute the environment;during the application process, the operator's body adhesion or inhalation dose can be reduced to avoid poisoning accidents; make high-toxic pesticides low-toxic and avoid poisoning of humans and cattle; it can control the release rate of the active ingredients in the granules and prolong the duration of the effect; easy to use, high efficiency. All in all, these incomparable characteristics make it a better agent.
Chlorpyrifos 5%GR is an organophosphorus insecticide, with contact, stomach action, fumigation effect, the mechanism of action is cholinesterase inhibited, the residual time on plant is short, but the residual period in the soil is long.
Applied for the prevention and treatment underground pests of crops such as peanuts, soybeans, vegetables, sugar cane, sweet potatoes, etc; and the control effect of the root crops of leeks and wheat midge insects is also particularly evident.
Different from other conventional granule product, Chlorpyrifos 5%GR takes advantage of fine powder of abamectin as a carrier can not only improve the efficacy but also increase the absorption and utilization of the active ingredient. Slowly released in the soil, long duration, prevention and controlling time.
