Kiwifruit root rot control methods

Kiwifruit root rot generally begins to develop in April. It is a severe period from July to September. It often occurs in soils with heavy mud and poor drainage.

Agricultural control

1 Cultivate disease-free seedlings. Kiwifruit seedlings are grown disease-free for many years. Fertilizers are mainly decomposed tillers or cakes. When the pH value is greater than 8, they cannot be cultivated, and they must be modified to make the pH value neutral or weakly acidic. Cultivation; 2 in the new garden, remove all plant residues in the soil; 3 avoid bounty flooding or string tree irrigation, conditional, available sprinkler irrigation or drip irrigation; 4 low-lying orchard drainage of bad orchards, in prolonged rainfall or heavy rain Afterwards, drainage should be conducted in time to reduce the humidity in the field; 5 Reasonable load. Some fruit trees are heavily overloaded due to excessive fruiting or using large fruit spirits, causing tree vigor to weaken and resistance to decline.

Chemical control

For susceptible adult orchards, use 0.8% bacteria to destroy 300 times or 40% carbendazim 400 times to irrigate roots. Each tree should be filled with 2 to 3 kilograms of liquid medicine, every 15 days, and even irrigation 2 to 3 This time, it can inhibit root rot and increase the yield per plant of kiwifruit. When the diseased plant was found, the root and neck soil was excavated, and the diseased part and a few sound parts were scraped off. After being sterilized with 0.1% mercury, the Bordeaux slurry was applied, and the new soil was covered after half a month. , to be coated with wax protection, and follow the application of decomposed water manure to restore the tree vigor.
