Pyrazolachlor is a chloroacetamide herbicide. Pyrazolomide is an inhibitor of long-chain fatty acid synthesis. It affects the cell division or tissue differentiation of weed seeds during germination and germination.

Diene ketone has strong reaction ability and can be derived from a variety of products. It is the raw material of fine chemicals, dyes, pharmaceuticals, pesticides, food and feed additives and additives. Acetyl diethylamine obtained by reaction of diene and diethylamine is an intermediate of organophosphorus insecticide phosphoramine; Acetylmethylamine obtained by reaction with methylamine is the intermediate of monocrotophos. Dienone reacts with ammonia to produce acetylacetamide, which is used to synthesize dye intermediates 1 - (4-chlorophenyl) - 3-methyl-5-pyrazolone and 1 - (4-sulfonylphenyl) - 3-methyl-5-pyrazolone; Dienone reacts with ethanol to produce ethyl acetoacetate, which is used to synthesize dye intermediates such as 1-phenyl-3-methyl-5-pyrazolone, 1 - (2,5-dichloro-4-sulfonylphenyl) - 3-methyl-5-pyrazolone, etc. From these intermediates, dye YONGGU yellow G, acid mordant jujube BN, neutral orange RL, neutral brown 5rl, neutral dark brown BRL, acid light yellow G, weak acid light yellow G, acid light yellow 2G, active light yellow k-6g, active light yellow m-5g, active light yellow x-6g, neutral peach BL, etc. can be prepared. 1-phenyl-3-methyl-5-pyrazolone and its derivatives are more used in the production of antipyretic analgesics antipyrine, aminopyrine, analgin, etc. Diene ketones can also be used in the synthesis of amino acids. Feed additive quinoethanol (kuaiyuling) can be prepared from diene, o-nitroaniline and ethanolamine. Dienes are used to synthesize a variety of heterocyclic compounds, such as pyrrole derivatives, isoxazole derivatives, pyrazolone derivatives, pyrimidine derivatives, thiazole derivatives, quinoline compounds, coumarin compounds and furan derivatives; Dienone can also react with a series of compounds to produce pyranone, pyridinone, dioxane, oxazine and flavonoids. Used as pharmaceutical intermediates, food preservatives, pigments and regulators.

Bubenmorpholine is mainly used to control cereal powdery mildew and banana leaf spot, and other fungal diseases, such as white, red and brown root disease, powdery mildew and coffee eye spot of rubber tree; Tea cake disease; It has good powdery mildew control effect on melons and white trees.

Clopidourea is a phenylurea cytokinin, which can affect the development of plant buds, accelerate cell mitosis, promote cell growth and differentiation, and prevent the abscission of fruits and flowers, so as to promote plant growth, precocity, delay the senescence of leaves in the later stage of crops and increase yield. It is mainly manifested in: ① the function of promoting the growth of stems, leaves, roots and fruits. For example, it can make leaves hypertrophy and increase production when used in tobacco planting. ② Promote results. It can increase the output of fruits and vegetables such as tomatoes (tomatoes), eggplants and apples. ③ Accelerate fruit thinning and defoliation. Fruit thinning can increase fruit yield, improve quality and make fruit size uniform. For cotton and soybeans, falling leaves make harvesting easy. ④ When the concentration is high, it can be used as herbicide. ⑤ Others. Such as the drying effect of cotton, sugar beet and sugarcane increase sugar content, etc.

Generally, there are two dosage forms of commercial antibacterial agent 401 and antibacterial agent 402, which can be used as non oxidizing bactericide for circulating cooling water. The use concentration of antibacterial agent 401 is 300mg / L and that of antibacterial agent 402 is 100mg / L. Allicin is easy to decompose and fail under alkaline conditions. It is not suitable for alkaline water or combined with chlorine.
