Be careful not to mix with copper containing fungicide and propargyrum.
Dicamba
belongs to the department of benzoic acid herbicides, have uptake conduction effect, has the significant control effect on the annual and perennial broadleaf weeds.
Dichlormid
1. as acetochlor protectant, it can be used for seed dressing, and can also be combined with herbicide spray for soil treatment.
Difenoconazole
Difenoconazole 95%TC is a kind of Systemic fungicide with a novel broad-range activity protecting the yield and crop quality by foliar application or seed treatment.
Diflufenican
The diflufenican is a selective contact and residual herbicide that can be applied pre-emergence and post-emergence. It can be absorbed through the shoots of the germinating seeding with limited translocation. Its mode of mechanism is via a bleaching action through inhibiting the carotenoid biosynthesis process, further blocking photosynthesis process and causing plant death. It is used for the treatment of some broad leaved weeds such as Stellaria media (Chickweed), Veronica Spp (Speedwell), Viola spp, Geranium spp (Cranesbill) and Laminum spp (Dead nettles). It has been approved for use on barley, durum wheat, rye, triticale and wheat. It can be used in combination with isoproturon or other cereal herbicides.

Dimethoate
Pure product is white crystal, industrial product is light yellow solid or light yellow liquid with garlic odor. m. P.52-52.5 ℃, relative density 1.277 (20 ℃). Refractive index n65d1.5334 (65 ℃), volatility 0.107mg/m3. The vapor pressure is 1.13 × 10-3pa (25 ℃). At room temperature, the solubility is 80% methanol, 70% acetone, 70% dichloromethane, 65% chloroform, 65% cyclohexanone, 60% benzene, 40% toluene, 6.5% xylene, 2.0% carbon tetrachloride, 0.1% petroleum ether, and 2.9% in water. It is stable in the acid medium chemical book, easy to hydrolyze in the alkaline medium, k = 6.8min-1.mol-1 (25 ℃), and heavy metal ions (copper, manganese, iron) have catalytic hydrolysis. The hydrolysis rate T1 / 2 in aqueous solution is as follows: > 100D (pH 4,21 ℃), 120h (pH 7,20 ℃), 6.5h (pH 9,70 ℃), 1min (pH 13,21 ℃). In the storage period, it will decompose slowly, the decomposition speed is related to the purity and temperature, the purity is high, the temperature is low, the decomposition speed is slow, 40% emulsifiable oil is stored at room temperature for one year, the content drops about 5%. The thermal stability is poor and isomerization occurs during heating.
Dimethomorph
Dimethomorph is a cinnamic acid derivative and a member of the morpholine chemical family. Dimethomorph is a mixture of E- and Z-isomers in the ratio of about 1:1 and only the Z-isomer has the fungicidal activity. It fungicidal activity works by the inhibition of sterol (ergosterol) synthesis. Dimethomorph is a systemic fungicide to protect against various fungal pathogens in vines and other crops.
Dinotefuran
Furosemide (the latest generation of super nicotine insecticides. Its chemical structure is quite different from the existing nicotine insecticides. Its tetrahydrofuran group has replaced the previous Chloropyridine group and chlorothiazolyl group, and it does not contain halogen elements. At the same time, its performance is different from that of nicotine.
Diquat Dibromide Monohydrate
Synonyms: 6,7-dihydrodipyrido[1,2-a:2',1'-c]pyrazinediium dibromide monohydrate; 6,7-dihydrodipyrido[1,2-a:2',1'-c]pyrazinediium dibromide; 6,7-dihydrodipyrido[1,2-a:2',1'-c]pyrazinediium bromide hydrate (1:2:1)
Emamectin Benzoate
Carbamate benzoate is a kind of non residual and pollution-free biological pesticide. It has a very high activity to the larvae of Lepidoptera and many other pests and mites. It has both stomach toxicity and contact killing effect. It has a very good effect at a very low dose (0.084 ~ 2G / HA). In addition, it has no harm to the beneficial insects in the process of pest control, which is conducive to the comprehensive pest control. In addition, it is also beneficial to the comprehensive pest control In addition, the insecticidal spectrum is expanded and the toxicity to human and livestock is reduced. Methaamamectin benzoate can enhance the function of neuroplasm, such as glutamate and GABA, so that a large number of chloride ions enter into nerve cells, resulting in the loss of cell function and disruption of nerve conduction. The larvae stop eating immediately after contact, causing irreversible paralysis and reaching the highest lethal rate within 3-4 days. Because of the close combination of abamectin benzoate and soil, it is not leached, nor accumulated in the environment. It can be easily absorbed by crops and permeated into the epidermis through movement and transfer, so that the applied crops have long-term residual effect. The second high peak of insecticidal death rate appears in more than 10 days, and it is rarely affected by environmental factors such as wind and rain.
