Custard apples are a delicious and nutritious tropical fruit but can be susceptible to various pests and diseases.
In this article, we’ll explore common pests that attack custard apples and discuss organic pest control methods to help you protect your precious fruit trees.
Common Pests That Attack Custard Apple Trees
Several pests can infest custard apple trees, including:
- Scale insects
- Potato leaf hoppers
- Annona seed borers
Whiteflies are tiny, white-winged insects that can cause damage to custard apple trees by sucking the sap from the leaves.
This sap-sucking weakens the plant and can lead to yellowing leaves, stunted growth, and reduced fruit yield.
Additionally, whiteflies excrete a sticky substance called honeydew, which can promote the growth of sooty mold on the tree.
Scale insects: Scale insects are small, sap-sucking pests that attach themselves to the stems, leaves, and fruit of custard apple trees.
They can cause leaf yellowing, leaf drop, and reduced plant vigor. Heavy infestations can lead to decreased fruit production and even tree death.
Mealybugs: Mealybugs are small, soft-bodied insects that feed on the sap of custard apple trees, causing leaf distortion, yellowing, and premature leaf drop.
They excrete honeydew, which can lead to sooty mold growth and attract ants, further complicating the infestation.
Potato leaf hoppers
Potato leaf hoppers: Potato leaf hoppers are small, greenish-yellow insects that feed on the sap of custard apple tree leaves.
Their feeding can cause leaf curling, yellowing, and necrosis, ultimately reducing the tree’s overall health and fruit production.
Annona seed borers:
Annona seed borers: Annona seed borers are larvae of certain moths that tunnel into the seeds of custard apple fruits.
This infestation can lead to fruit drop and damage to the seeds, making the fruits unappealing and reducing their market value.
Aphids: Aphids are small, soft-bodied insects that feed on the sap of custard apple trees.
They can cause leaf curling, yellowing, distortion, and a reduction in tree vigor and fruit production.
Like whiteflies and mealybugs, aphids also excrete honeydew, leading to sooty mold growth and attracting ants.
These pests can cause significant damage to your custard apple trees and reduce your fruit yield. Luckily, there are organic pest control methods to help you manage these pesky invaders.
Organic Pest Control Methods
Pyganic is an organic pesticide derived from chrysanthemum flowers. It is effective against various pests, including whiteflies, aphids, and potato leaf hoppers.
Pyganic works by targeting the nervous systems of pests, causing paralysis and death.
- OMRI listed; meets National Organic Program (NOP) requirements
- Can be used throughout the growing season, on many different garden sizes, up to the day of harvest
- Created from botanically-derived pyrethrins, making it the ideal insecticide product for your garden
- Can be used on many different types of plants, including tomatoes, peppers, cucumbers, and celery
- Kills more than 200 types of crop-damaging insects, including beetles, mites, roaches, and ants
It is essential to use Pyganic responsibly, as it can harm beneficial insects, such as butterflies and bees. To protect these helpful creatures, spray Pyganic early in the morning before they start flying around.
Remember to follow the label instructions for the proper application rate and safety precautions.
Mixing and Applying Pyganic with a Backpack Sprayer
Using a backpack sprayer to apply organic insecticides like Pyganic is an effective way to treat pests on your custard apple trees.
Follow these steps to mix and apply Pyganic using a backpack sprayer:
Read the label: Before you begin, thoroughly read the Pyganic label to understand the recommended application rate and safety precautions. The label will provide information on how much Pyganic concentrate to mix with water to achieve the desired concentration.
Prepare the backpack sprayer: Make sure your backpack sprayer is clean and free of any residue from previous applications. If necessary, rinse the sprayer with water to ensure it’s clean.
Measure the Pyganic concentrate: Based on the label instructions, measure the required amount of Pyganic concentrate for your specific pest problem and tree size. Use a measuring cup or graduated cylinder for accuracy.
Fill the backpack sprayer: Fill the backpack sprayer halfway with water. Then, slowly pour the measured Pyganic concentrate into the sprayer. This will help to ensure that the concentrate mixes thoroughly with the water.
Mix the solution: After adding the Pyganic concentrate, fill the backpack sprayer with the remaining water. Close the sprayer and gently shake or agitate it to mix the solution evenly.
Put on safety gear: Before applying Pyganic, wear appropriate safety gear, including gloves, goggles, and long sleeves. This will protect you from potential skin irritation or eye contact with the insecticide.
Apply Pyganic: With the backpack sprayer on your back, pump the handle to create pressure in the sprayer. Then, using the spray wand, apply the Pyganic solution evenly to the custard apple tree, focusing on the leaves, branches, and trunk. Be sure to cover both the top and bottom of the leaves, as pests often hide on the underside.
Clean the backpack sprayer: After applying the Pyganic solution, thoroughly rinse the backpack sprayer with water to remove any remaining insecticide. This will prevent cross-contamination and ensure the sprayer is ready for future use.
Remember to apply Pyganic early in the morning before butterflies and bees start flying around, as it can be harmful to beneficial insects.
Additionally, be prepared for consistent applications of Pyganic to effectively control pests, as it is an organic solution.
