Fluorine-Containing Methylbenzene products can be used as herbicides in the manufacture controlling wheat fields, cotton fields and other broadleaf weeds and perennial weeds. It can also be used in the manufacture of antipsychotics drugs.

1. Carp and carp restocking accounts for 70% to 80%, and production accounts for 60% to 70%. Large-size fish species are managed using adult fish ponds. Catfish and carp species began to be caught in May and they were caught 6 to 7 times in a year. After the arrest, the fish species were magnified and enlarged. Generally, the number of fish species to be added was roughly equal to the number of species caught.
2. The main measures for the rearing of the farmer's home-grown fertilizer are that the general pond is relatively large (10 to 30 mu), which is suitable for introducing large amounts of domestic sewage or farmyard manure.
3. To improve water quality, make full use of farmyard manure residue, pay attention to polyculture of organically rotted tilapia, silver carp, etc. They can fully utilize pond feed resources than carp and carp.
4. The combination of fish, livestock, poultry, and agriculture should be carried out to develop a “comprehensive fish farming†and “fish, pig, and vegetable†combination, and to implement a biological cycle to make full use of energy and maintain ecological balance.
The Fluorine-Containing Methylbenzene products must be kept under seal, once exposed to light will immediately cause discoloration. It should also be stored in a cool, ventilated warehouse, away from fire and heat. Compartment temperature should not exceed 30 ℃. And make the appropriate technical measures for fire and explosion. Products will Decomposition by high fever and emit toxic gases, such as carbon monoxide, carbon dioxide, hydrogen fluorid. Due to ts vapor is heavier than air, it can spread from low place to far away places. In case of fire conditions, should not fire with water. In case of a small amount of leakage should be evenly sprayed with dilute hydrochloric acid. In case of large spills should build a causeway or trenching asylum. The transfer pump to tankers or exclusive collector, recycling or shipped to the waste disposal sites.
The polyculture technology based on carp carp
The filter-feeding fish carp and carp are mainly fish cultures, and other fish are properly mixed. Special attention is paid to the fish that are mixed with organically rotted fish. The main method of applying farmer's home fertilizer during the breeding process
