What to Do When Passion Fruit Suffers Herbicide Damage? The Latest Remedies

Passion fruit is a very common fruit, and its planting area in our country is very large. When growing passion fruit, many fruit farmers spray some herbicides to clear weeds, but due to improper spraying and other reasons, passion fruit is highly susceptible to herbicide damage, seriously affecting yield and fruit quality. So what should be done when passion fruit suffers herbicide damage? Below, the editor will give you a brief introduction. Let's take a look together!

1. Symptoms of Herbicide Damage

There are many reasons that cause passion fruit to suffer herbicide damage. For example, improper selection of herbicides, contaminated spraying equipment, soil residues affecting crop growth, as well as various environmental reasons. After passion fruit suffers herbicide damage, the plants will show phenomena such as dwarfing, deformity, yellow leaves and shriveling. The growth rate of passion fruit plants will decline noticeably, or even stop growing, and in severe cases it will cause the passion fruit plants to die. However, different types of herbicides will produce different symptoms of herbicide damage.

2. Remedial Measures for Herbicide Damage

In the early stage of herbicide damage, if the damage is caused by spraying leaves or plants and is discovered in time. At this time, because the spray liquid has not yet completely penetrated into the interior of the plant, clean water can be used for flushing and irrigation, and then an appropriate amount of fertilizer should be applied to neutralize the acidity of the herbicide and wash away the toxic substances on the plant. If the herbicide damage is relatively light, then the damaged branches can be cut off in time, and the application amount of quick-acting fertilizer should be increased. Apply more organic fertilizer, because organic matter can adsorb herbicides, reduce the activity of herbicides, and provide sufficient nutrients for passion fruit.

If a herbicide that inhibits or interferes with the growth of passion fruit is used, then after the herbicide damage occurs, some growth regulators should be sprayed appropriately, such as gibberellin, etc. To slow down the degree of herbicide damage. If the symptoms of herbicide damage are relatively serious, then the land should be plowed appropriately, the soil should be exposed to the sun for thorough sunning, and the soil should be disinfected through sunlight. After ensuring that the herbicide damage has disappeared, do a good job of replanting.

3. Preventive Measures

First, we need to choose a good herbicide. The herbicide must not only ensure the weeding effect, but also be careful not to affect the growth of passion fruit and not produce residues. Then control the application amount, do not use excessively, and avoid too high a concentration. Herbicides should not be applied in environments with excessively high or low temperatures, high humidity and strong winds. When spraying, try to aim at the ground. Then note that it is best not to use systemic herbicides such as glyphosate and other organophosphorus herbicides. After spraying, clean the spraying equipment in time to avoid causing herbicide damage when spraying other pesticides.

The above is a brief introduction to what to do about herbicide damage in passion fruit. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
