Due to the high humidity in the field every year, a variety of diseases occur most commonly and harm the most serious period, once the disease control is not ideal, it will cause a huge yield loss, or even no harvest in serious cases. Today, I recommend a combination of the most powerful fungicides, which can control more than 30 diseases and completely eradicate them in just two times. An excellent combination of fungicides is trifloxystrobin·tebuconazole。
1.sterilization principle
Amoxime · tebutazol is a compound fungicide which is composed of amoxime ester + tebutazol. Oxime ester is a kind of respiratory inhibitor, which can prevent ATP synthesis of cells through electron transfer between cytochrome B and C1, thus inhibiting mitochondrial respiration and exerting bacteriostatic effect. It has a good protective and therapeutic effect on fungi such as ascomycetes, hemipycetes, basidiomycetes and oomycetes.
Tebutazolol is a triazole fungicide against pathogenic fungi ergosterol inhibitor, mainly by inhibiting the oxidation demethylation reaction of ergosterol intermediates, to achieve the purpose of killing bacteria. After mixing the two, the synergistic effect is very obvious, with long duration of effect, strong permeability, good conductivity, flexible use and other characteristics, has a particularly significant control effect on a variety of fungal diseases.
2. Common dosage forms
Common dosage forms are 75% water dispersible granule, 30%, 36%, 42%, 48% suspension agent.
3. Main features
(1) Wide sterilization spectrum: The combination of ascomycetes, imperfect fungi and basidiomycete fungi and oomycetes, such as powdery mildew fungus diseases, stem blight, early blight, anthracnose, rice, rice blast and sheath blight disease, leaf spot, scab, scab, spot disease leaves, leaf spot disease, white rot, black blain, leaf spot disease, and so on more than 30 of downy mildew and epidemic disease have good control effect.
(2) Cure thoroughly: the combination is composed of two fungicides with completely different mechanism of action. It has good internal absorption and can protect, treat and eradicate a variety of diseases.
(3) small impact on the environment: the two agents are low toxicity, low residual fungicides, high activity, low dosage, small impact on people, livestock, fish, bees and other environmental organisms.
(4) Stimulate crop growth: the combination can also regulate the absorption of calcium in crops, prevent the occurrence of physiological calcium deficiency, regulate the absorption of nitrogen and phosphorus in crops, so that crops grow more healthy, high yield and good quality.
4. Use method
(1) To prevent and treat rice blight, rice smut, rice smut, rice grain smut and other diseases, use 75% xime bacteria · tebutazol water-dispersing granule 13-15 g/mu, adding 30-50 kg of water, which can be sprayed 5-7 days before rice rupture and once in full heading stage, and can better prevent and treat these diseases.
(2) To prevent and control wheat blight, powdery mildew, rust, fusarium graminearum and other diseases, 30% xime bacteria · tebutazol suspension 36-45 ml/mu, add 30 ~ 50 kg of water, spray once in seedling stage, flowering stage of wheat, can quickly control the harm and spread of the above diseases.
(3) The prevention and control of corn big and small spot disease, gray spot disease and other diseases, can be used 30% oxime bacteria · tebutazol suspension 36-45 ml/mu, add 30 ~ 50 kg of water, in the corn big bell stage and filling stage spray once, can prevent the occurrence and spread of the above diseases.
(4) the prevention and control of apple spot deciduous disease, anthracnose, brown spot, ring, etc., in the early stage of the disease, with 75% water dispersive agent 4000 ~ 5000 times liquid spray.
(5) the prevention and control of pepper anthracnose, powdery mildew, black mildew, blight in the early stage of the disease, with 75% oxime myloxyl · tebutazol water dispersive granules 3000 times liquid spray, 7~10 days spray 1 times, even spray 2~3 times. Prevention and control of other diseases can refer to the above crop disease control methods.
