Carbendazim can be used in a variety of ways. In addition to conventional spraying, it can also be used for root irrigation, smearing, soaking, and soil disinfection.
(1) Root diseases of deciduous fruit trees
On the basis of removing diseased root tissue, use liquid medicine to irrigate the roots of fruit trees. The amount of watering liquid medicine varies with the size of the tree. Generally, the main root area of the tree is moistened.
Generally use 250-300 times liquid of 25% wettable powder,
Or 40% wettable powder or 40% suspending agent 400-500 times liquid,
Or 50% wettable powder or 50% water dispersible granule or 50% suspending agent or 500g/L suspending agent 500~600 times liquid,
Or 700-800 times of 75% water dispersible granules,
Or 80% wettable powder or 80% water dispersible granule 800~1000 times liquid,
Or 1000-1200 times of 90% water dispersible granules for watering.
Root disease prevention and control is better in early spring, but overall it should be based on early detection and early treatment.
(2) Apple disease
When it is rainy and humid before and after flowering, or in orchards in scenic green areas, firstly spray once before flowering and after flowering to effectively prevent and control flower rot, rust, and powdery mildew; then start spraying continuously from about 10 days after flowering Medicine, once every 10 days, spray 3 times in a row and then bag, continue to spray 4 times after bagging (interval of 10-15 days); without bagging apples, spray once every 10-15 days. Continuous spraying for 7 to 10 times has a good control effect on ring fruit rot, anthracnose, brown spot, brown rot, scab, and water rust.
The specific spraying time and frequency can be flexibly controlled according to the rainfall, more rain and less rain; when spraying continuously, it is best to alternately use or mix with different types of pesticides. Alternate use or mixed use of captandan, pyraclostrobin, tebuconazole and other agents has better effect.
Carbendazim generally uses 250 to 300 times the liquid of 25% wettable powder,
Or 40% wettable powder 400~500 times liquid,
Or 50% wettable powder or 50% water dispersible granule or 40% suspending agent 500-600 times liquid,
Or 50% suspending agent or 500g/L suspending agent 600-800 times liquid,
Or 75% water dispersible granules 800 to 1000 times liquid,
Or 80% wettable powder or 80% water dispersible granule 1000~1200 times liquid,
Or evenly spray 90% water dispersible granules 1200-1500 times liquid.
After harvesting the unbagged apples, soak the fruit with the above medicinal liquid for 20-30 seconds, remove it and dry it for storage and transportation, which also has a good control effect on the post-harvest fruit rot.
(3) Diseases of pear trees
In orchards in scenic green areas, spraying once before flowering and after flowering can effectively prevent and control rust.
In the future, it will be sprayed continuously from about 10 days after the flower falls, once every 10 to 15 days, with mycoconazole, diconazole, difenoconazole, tebuconazole, captan, and mancozeb in a fully complex state. , Pyraclostrobin and other agents are used alternately or mixed, and continuous spraying is required for 7 to 10 times, which can effectively control scab, ringworm, anthracnose, and brown spot.
The specific spraying time and frequency are flexibly controlled according to the rainfall conditions, more rain and more spray, less rain and less spray. The spraying multiple of carbendazim is the same as that of "apple disease".

Then continue to spray from the middle and late stage of fruit expansion, once every 7 to 10 days, and spray 3 to 5 times in a row to effectively prevent and control anthracnose, as well as house blight and brown spot.
The spraying multiple of carbendazim is the same as that of "apple disease", and it should be used alternately or mixed with different types of agents.
(5) Peach tree disease
In the blooming period of flower buds, spray 100-150 times of 25% wettable powder once,
Or 40% wettable powder 150~200 times liquid,
Or 50% wettable powder or 50% water dispersible granule or 40% suspending agent 200~300 times liquid,
Or 75% water dispersible granules or 80% wettable powder or 80% water dispersible granules or 50% suspending agent or 500g/L suspending agent 300-500 times liquid,
Or 500-600 times of 90% water dispersible granules to effectively prevent and control leaf shrinkage.
Then continue spraying from about 20 days after flowering, once every 10 to 15 days, alternately or mixed with different types of chemicals, and spray 3 to 4 times in a row, which can effectively prevent and control scab, anthracnose, and fungal perforation. and rust;
In the orchards with severe brown rot disease in previous years, the prevention and control of spraying began 1.5 months before the fruit was harvested, once every 10 days, and sprayed 2 to 3 times in a row to prevent anthracnose and rust;
In orchards with severe rust disease in previous years, spraying began when the disease spots first appeared on the leaves, once every 10 days, and sprayed twice in a row.
After flowering, the spraying multiple of carbendazim is the same as that of "apple disease".

Matters needing attention Carbendazim can be mixed with non-alkaline insecticides and acaricides in a tank, but cannot be mixed with alkaline pesticides such as Bordeaux mixture and lime sulfur.
When spraying continuously, pay attention to alternate or mix with different types of fungicides. Suspension dosage forms may sometimes have some precipitation, and use after shaking will not affect the efficacy.
Since carbendazim residues have certain reproductive toxicity (males), some fruit areas have restricted the use of medicaments containing carbendazim ingredients, so the specific use should be selected according to local management requirements. The safe interval for use on both apple and pear trees is 28 days, with a maximum of 3 applications per season.
