Due to high temperature, heavy rainfall, and high field humidity, it is also the period when many diseases are most common and most harmful. Once the disease control is not ideal, it will cause huge yield losses, and even total crop failure in severe cases. Today, I will recommend you a strongest fungicide combination that can prevent and control more than 30 diseases, and only needs two times to completely eradicate the disease. This excellent fungicide combination is trifloxystrobin + tebuconazole.
1. Sterilization principle
Trifloxystrobin Tebuconazole is a composite fungicide made by mixing trifloxystrobin + tebuconazole. Trifloxystrobin is a respiratory inhibitor that prevents cell ATP synthesis through electron transfer between cytochrome b and c1, thereby inhibiting its mitochondrial respiration and exerting an antibacterial effect. It has good protection and therapeutic effects on fungi such as ascomycetes, deuteromycetes, basidiomycetes and oomycetes.
Tebuconazole is a triazole fungicide that inhibits ergosterol in pathogenic fungi. It kills pathogens by inhibiting the oxidative demethylation reaction of ergosterol intermediates. After the two are mixed, the synergistic effect is very obvious. It has the characteristics of long-lasting effect, strong permeability, good conductivity, and flexible use. It has a particularly significant control effect on a variety of fungal diseases.
2. Common dosage forms
This combination is currently produced by many manufacturers. Common dosage forms include 75% water-dispersible granules, 30%, 36%, 42%, and 48% suspensions.
3. Main features
(1) Broad fungicide spectrum: This combination has good control effects on fungal diseases such as powdery mildew, vine blight, early blight, anthracnose, rice smut, rice blast, sheath blight, brown spot, black spot, scab, leaf spot, leaf spot, white rot, black pox, leaf spot, and more than 30 other diseases such as downy mildew and blight.
(2) Thorough treatment: This combination is a combination of two fungicides with completely different mechanisms of action. It has good systemic properties and has protective, therapeutic and eradication effects on a variety of diseases.
(3) Small impact on the environment: Both agents are low-toxic and low-residue fungicides with high activity and low dosage, and have little impact on humans, livestock, fish, bees and other environmental organisms.
(4) Stimulate crop growth: This combination can also regulate the absorption of calcium by crops, prevent the occurrence of physiological calcium deficiency, regulate the absorption of nitrogen and phosphorus by crops, and make crops grow healthier, with high yield and good quality.
4. Usage
(1) To prevent and control rice sheath blight, rice false smut, rice grain smut and other diseases, use 75% trifloxystrobin·tebuconazole water dispersible granules 13-15 g/mu, add 30-50 kg of water, and spray once 5-7 days before rice burst and at the heading stage, which can effectively prevent and treat the above diseases.
(2) To prevent and control wheat sheath blight, powdery mildew, rust, fusarium head blight and other diseases, use 30% trifloxystrobin·tebuconazole suspension 36-45 ml/mu, add 30-50 kg of water, and spray once at the wheat seedling stage and flowering stage, which can quickly control the damage and spread of the above diseases.
(3) To prevent and control corn diseases such as large and small spot disease and gray spot disease, 30% trifloxystrobin·tebuconazole suspension 36-45 ml/mu can be used, diluted with 30-50 kg of water, and sprayed once during the corn flaring stage and the grain filling stage to prevent and control the occurrence and spread of the above diseases.
(4) To prevent and control apple leaf spot disease, anthracnose, brown spot disease, ring rot disease, etc., spray with 75% water dispersible granules 4000-5000 times diluted.
(5) To prevent and control pepper anthracnose, powdery mildew, black mold, and damping-off disease, spray with 75% trifloxystrobin·tebuconazole water dispersible granules 3000 times diluted, spray once every 7-10 days, and spray 2-3 times in a row. For the prevention and control of other diseases, please refer to the above crop disease prevention and control methods.
