How to Treat Grapevine Borers
Summary: This article introduces topics related to the treatment of grapevine borers and effective methods to prevent them in the context of flower cultivation. Details are as follows:
Grapevine borers can easily damage the trunk, affecting growth and leading to reduced yield. It is important to prevent borers and address them promptly when they first appear in small numbers, otherwise, they can cause significant harm later on. Timely pruning of damaged, hollow branches, thoroughly cleaning the garden, burning bad leaves to prevent further spread, capturing虫卵 (egg masses), and taking chemical treatments are some measures. Let's delve into details together, including pruning diseased branches, capturing虫卵, and chemical treatments.
1. Pruning Diseased Branches
Branches that have undergone pathological changes should be completely pruned, cutting more towards the main branch to ensure no harmful branches remain. Rotting and spoiled fruit should be cut off to prevent infection of other fruits. At the same time, garden cleaning should be carried out to prevent the recurrence of pest infestations the following year. Withered branches, fallen leaves, and diseased fruit should be burned or buried deeply, thoroughly repairing the trunk. You can apply lime to the trunk to avoid pest damage.
2. Capturing Egg Masses
You can use a small hook to pull out the borers from the hollow branches and place calcium phosphide granules in the borers' holes, then block the holes with soil to create a sealed environment to kill the pests. If the holes in the intersecting branches are interconnected, you can tie a cotton ball to the end of a thin wire or wooden stick, dip the cotton ball in the pesticide, and insert it into the branch to poke out the borers.
3. Chemical Treatments
Address the borers promptly when they appear to prevent later outbreaks. You can use科比600 times plus敌杀死1500 times, or 福星8000 times plus 敌杀死1500 times for control. Alternatively, you can use 20% cypermethrin emulsifiable oil 3000 times liquid, 20%菊杀 or 10%菊马 emulsifiable oil 1000 times, 10% 多来宝 suspension agent 2000 times liquid, or 21%灭杀毙 emulsifiable oil 2000 times, etc., to kill the pests.
The above shares the specific content of how to treat grapevine borers and effective methods to prevent them, for everyone's reference and operation.
