Dazomet
Indoxacarb
Pymetrozine
Pyriproxyfen
English name: dazomet
Chemical name: 3,5-dimethyltetrahydro-1,3,5,(2H)-thiodiazinothione
Chemical formula: C5H10N2S2
molecular weight: 162.3
Physic-chemical property: The pure product is white crystal, odorless, its melting point is 99.5℃ (decomposition), its solubility in water is 3,000ppm at 20℃, and it is easy to decompose in aqueous solution, especially at 45℃, and it will decompose rapidly when exposed to strong alkali or strong acid.
Toxicity: low
Specification: 98% TC
Formulation: 98% granule.
Application: "dazomet" is an environment-friendly broad-spectrum comprehensive soil fumigation disinfectant with high efficiency, low toxicity and no residue. When applied to moist soil, it produces a gas of methyl isothiocyanate, which spreads rapidly to the soil particles, effectively killing various nematodes, soil-borne pathogens (fungi and bacteria), underground pests (soil insects) and annual weed seeds in the soil, thus achieving the effect of cleaning the soil, especially suitable for soil disinfection in perennial successive crops.
Package: 20 kg per bag or 600 kg per bag.
English name: indoxacarb
Chemical name: methyl (S)-N-[7-chloro-2,3,4a,5-tetrahydro-4a-(methoxycarbonyl)indeno[1,2-e][1,3,4]oxadiazin-2-ylcarbonyl]-4’-(trifluoromethoxy)carbanilate
Chemical formula: C22H17ClF3N3O7
Molecular weight: 527.83
Physic-chemical property: White powder-like solid
Specification: 95% TC
Formulation: 150 g/l SC, 30%WG, 15%EC, 20%EC.
Application: it is suitable for controlling cabbage caterpillar, prodenia litura, cotton bollworm, leaf roller and cydia pomonella on beet.
Package: 25 kg per cardboard drum
English name: Pymetrozine
Chemical name: (E)-4.5-dihydro-6-methyl-4-(3-pyridylmethylene amine)-1,2,3-triazine-3(2H)-ketone
Chemical formula: C10H11N5O
Molecular weight: 217.23
Physic-chemical property: the pure product is colorless crystal with melting point of 217℃ and density of 1.36(20℃). Solubility (g/l): water
0.29 (25°C) ethanol 2.25 (20°C), stability: hydrolysis DT50 at pH=1 for 4.3 days, hydrolysis DT60 at pH=5 for 25 days.
Specification: 96% TC
Formulation: 25%WP. 50%WG
Application: pymelozine is a highly selective insecticide for the control of pests with sucking mouthparts. Pymelozine can control aphids, planthoppers, leafhoppers and other pests on outdoor crops such as lettuce and leaf herbs; it can penetrate the leaves of green plants and make systematic transmission in plants. Although pymetrozine has no knock-down toxicity, it can quickly prevent aphids from feeding and achieve the effect that aphids are no longer harmful.
Package: 25 kg per cardboard drum.
English name: Pyriproxyfen
Chemical name: 4-Phenoxyphenyl (R/S)-2-(2-pyridyloxy)propyl ether
Chemical formula: C20H19NO3
Molecular weight: 331.5
Physic-chemical property: The product is crystal with melting point of 45-47℃, relative density of (d, 20)1.23, and solubility (20-25℃(8/kg), ethane 400, methanol 200 and xylene 500.
Specification: 95% TC
Formulation: 10%EC(w/v), (5% pyriproxyfen+15%methrin)EC
Application: it is a diphenyl ether insecticide, which is an insect growth regulator for controlling cockroaches. It is mainly used to control pests of public health significance, such as cockroaches, mosquitoes and flies.
Package: 25 kg per cardboard drum.

The content of soil organic matter represents the level of soil fertility. It is one of the important indicators to measure the level of soil fertility. It can promote the formation of soil aggregates, improve the conditions of soil physical, chemical and biological processes, and improve the absorption and buffering properties of soil. If the soil organic matter is too low, the soil immunity will be low, and it is easy to harden, acidify, and the crops are easy to get sick.

Soil improvement: symptoms and control of cabbage clubroot
Chinese cabbage clubroot disease is caused by Brassica campestris. After the plant is infected by Chinese cabbage root swelling fungus, its soil roots and underground stems will form tissue swelling tumors. In the case of slight impact, the appearance symptoms of the aboveground parts of Chinese cabbage are not obvious. In severe cases, the absorption of nutrients and water transportation of Chinese cabbage are interrupted, and the aboveground parts wilt due to malnutrition, showing varying degrees of yellowing. If the seedlings are young, some of them will droop, leading to premature death.

Soil improvement: the action principle and influence mechanism of fumigant (Mianlong) on soil
Methyl isothiocyanate (MITC) is the decomposition product of Mianlong. The parent pesticide was applied to the soil before planting and sowing, and rapidly decomposed into MITC in the form of mole to mole in the presence of water. MITC is a multi-purpose fumigant, which is used to resist the activity of plant pathogenic nematodes, weeds, oomycetes and a variety of plant pathogenic fungi through a non selective enzyme inhibition mechanism. MITC can also apply granular product dazomet (trade name LongXin;) Generated in soil. Its half-life ranges from hours to days, depending on environmental conditions. MITC is unstable and may be decomposed into methylamine through thiocarbamate in water. A faster hydrolysis rate is obtained at a lower pH level.
