Difenoconazole, a triazole fungicide, is a sterol demethylation inhibitor with high efficiency, broad spectrum, low toxicity and low dosage. It is an excellent variety of triazole fungicides with strong internal absorption. It can destroy the structure and function of pathogen cell membrane by inhibiting the biosynthesis of ergosterol in pathogen cells. It is used in fruit trees, vegetables, wheat, potatoes, beans, etc Cucurbits and other crops have good protection and treatment effects on vegetables, fruits and other fungal diseases, and have the characteristics of "three no" (no pollution of the environment, no pollution of agricultural products, no killing of natural enemies). They are ideal fungicides for controlling citrus scab, leaf spot and other crop resistant diseases in China and even in the world.

Indole exists in feces, coal tar, jasmine oil and Neroli oil. It is colorless, lobular or plate-shaped crystal. It has strong fecal odor. The pure product has fresh flower odor after dilution. It is soluble in hot water, benzene and petroleum. It is easily soluble in ethanol, ether and methanol. It can volatilize with water vapor. It turns red when placed in air or visible light, and resinifies. It is weakly acidic and forms salt with alkali metals, It is resinified or polymerized with acid. The highly diluted solution has jasmine fragrance and can be used as perfume. Indole is an important organic raw material and fine chemical product. Its homologues and derivatives widely exist in nature, mainly in natural flower oil, such as jasmine, sweet orange, white lemon, pomelo peel, orange, bitter orange, Narcissus, vanilla, etc. It can be widely used in jasmine, Syringa, orange blossom, gardenia, honeysuckle, lotus, Narcissus, Yilan, orchid, and prune.

Zineb is a broad-spectrum and protective bactericide. It can be used to control a variety of diseases of rice, wheat, vegetables, grapes, fruit trees, tobacco and other crops, such as wheat rust, corn leaf spot, tea red star disease, tobacco blight, anthrax, wild disease, peanut brown spot, potato blight, scab, black nevus, apple, pear, peach, citrus, grape, vegetable and so on.

Fluxioxonil, trade name maxim, etc. are bactericides developed and produced by Novartis. Its mechanism is to inhibit the protein activating enzyme PK – Ⅲ (kinase – Ⅲ) with signal function in the process of osmotic induction transmission, resulting in the increase of the concentration of nonphosphorylated regulatory protein, Thus, the secretion of osmotic sensitive cell division agent activated protease is abnormal, which eventually leads to the death of bacteria. Because of its unique action mechanism, it has no cross resistance with existing fungicides. It is a kind of pyrrole fungicides with great development prospect.

Beetning is suitable for controlling broad-leaved weeds in beet field, such as Zoysia, Chenopodium, mustard, wild oats, wild sesame, wild radish, shepherd's purse, hyacinth, weasel petal flower, niutengju, etc.
