The allocation of Bordeaux mixture on the three major fruit trees

First, the application of Bordeaux mixture in apple trees

Early defoliation of apple: In the first half of the first half of the disease (from the end of June to the beginning of July), spray an equal amount of 200 times Bordeaux mixture, and then spray once every 15-20 days, the effect is very good.

Apple dry rot sprayed 2:2:200~240 times Bordeaux mixture in May-June;

Apple anthracnose sprayed 1:2:200 times Bordeaux mixture from the young fruit period (about late May), and then sprayed once every 10-15 days, continuously spraying 3-4 times;

Apple rust is sprayed twice the amount of Bordeaux mixture after germination to the young fruit period;

Apple scab is sprayed 1:1.5~2:160~200 times Bordeaux mixture in June-July;

Apple brown rot is sprayed 2-3 times 1:1:160~200 times Bordeaux mixture in the onset period (September-October);

Apple plague rot is sprayed 2-3 times in the period from June to July.

Second, the application of Bordeaux mixture on grapes

Grape downy mildew: spray the first dose of the virus before the initial infection, and then spray once every half month 1:0.7:200 times Bordeaux mixture, continuous spraying 2-3 times, effective for the disease;

Grape rust in the early stage of the disease spray 1:0.7:200 times Bordeaux mixture;

Grape gray mold in the early stage of the disease in time to cut off the diseased spikes, and spray half of the 300 times Bordeaux mixture;

Grape black pox is sprayed 1:0.5:250 times Bordeaux mixture at the beginning of the disease;

Grape black rot is sprayed 1:0.7:200 times Bordeaux mixture before flowering, after flowering and during fruit growth period to protect the fruit and prevent the onset of leaves and shoots.

In the early stage of the disease, grape brown spot disease combines prevention and treatment of black pox and anthrax, and sprays 1:0.7:200 times Bordeaux mixture once every half month, continuously spraying 2-3 times.

Third, the application of Bordeaux mixture in pear trees

Pear scab: spray 1:2:200 times Bordeaux mixture before flowering and after flowering, and then spray once every 15-20 days to protect inflorescences, young shoots and leaves;

Pear brown spot disease: Spray 2:2:160~200 times Bordeaux mixture in the germination stage, spray once every 10 days, and spray 2-3 times continuously;

Pear black spot disease is sprayed 1:2:160-200 times Bordeaux mixture in the end of April to early July, and then sprayed once every 10 days, continuously spraying 7-8 times;
