What about the drug damage of passion fruit?

Passion fruit is a very common fruit, and its planting area is very large in our country. When planting passion fruit, many fruit growers will spray some herbicides to remove weeds, but due to improper spraying and other reasons, passion fruit is very vulnerable to herbicide damage, seriously affecting the yield and fruit quality. So what should we do if passion fruit is damaged by medicine? The following editor will give you a brief introduction, let's have a look!

1. Symptoms of drug damage

There are many reasons that lead to drug damage to passion fruit. For example, improper selection of herbicides, contamination of pesticide application equipment, impact of soil residues on crop growth, environment and other reasons. After being damaged by drugs, passion fruit will lead to dwarfing, deformity, yellow leaves, shrinkage and so on. The growth rate of passion fruit plant will obviously decrease, or even stop growing, and in serious cases, it will lead to the death of passion fruit plant. However, different drug injury symptoms can occur due to the type of herbicide.

2. Remedial measures for drug damage

In the early stages of drug damage, if the damage is caused by spraying on leaves or plants and is found in time. At this time, because the solution has not yet completely penetrated into the plant, it can be irrigated with clean water, and then an appropriate amount of water can be applied to neutralize the acidity of the herbicide and wash away the toxic substances on the plant. If the drug damage is mild, then the branches of drug damage can be cut off in time to increase the application amount of available fertilizer. Apply more organic fertilizer, because organic matter can absorb herbicides, reduce the activity of herbicides, and provide adequate nutrition for passion fruits.

If herbicides that inhibit or interfere with the growth of passion fruit are used, some growth regulators, such as gibberellin, should be sprayed properly after the damage occurs. Slow down the degree of drug damage. If the symptoms of drug damage are more serious, the soil should be ploughed properly, the soil should be exposed to the sun, and the soil should be disinfected by sunlight. After ensuring that the drug damage disappears, do a good job of replanting.

3. Preventive measures

First of all, we need to select herbicides, herbicides should not only ensure the effect of weeding, but also pay attention to the growth of passion fruit will not be affected, and will not produce residues. Then control the consumption, do not overdose, avoid excessive concentration. Herbicides should not be used in an environment where the temperature is too high and too low, high humidity and strong wind. When spraying, spray as far as possible on the ground. Then it is best not to use glyphosate and other organophosphorus internal inhalation herbicides, and clean the spraying utensils in time after spraying to avoid drug damage when spraying other pesticides.
