Common diseases and insect pests of asparagus

Asparagus is a common vegetable, which is widely planted in China. At the same time, China also grows the most asparagus in the world. Some insect pests are inevitable in asparagus, so let's take a look at what diseases are more common with the pro-agriculture network and how to solve them.

1. Brown spot

Brown spot is not only a disease that does great harm to asparagus, but also a frequent disease, which is mainly concentrated in the stem. When the disease occurs, the stem will first appear brown spots, yellow in summer, black in winter, and then slowly spread together, causing the whole plant to turn yellowish brown until withered. 50% carbendazim wettable powder 500 times or 50% carbendan 800 times solution has a good effect on the prevention and control of brown spot.

2. Stem rot

Stem rot mostly occurs on young bamboo shoots, the time is mostly concentrated in the rainy season, and the cause is mostly caused by excessive humidity. At the initial stage, it will slowly appear in the form of water stains on the young bamboo shoots. at this time, the newly unearthed parts actually have a tendency to rot, and the unearthed parts will gradually appear white filamentous mildew spots, which will spread the disease on a large scale if not handled properly. It is recommended that 64% disinfectant alum wettable powder 500 times solution should be used for prevention and control, and soil disinfection must be done at the initial stage of planting.

3. Night moth and other insects

The harm of this kind of insects to asparagus is relatively large, which is a highly destructive insect pest. Its main goal is to find the fresh and tender parts and gnaw them directly, and the occurrence time is mostly concentrated in summer. When these visible bugs are found on asparagus, they must be disposed of in time, otherwise it will seriously harm the growth and development of asparagus. 1000 times of trichlorfon crystal solution can be selected, which is a relatively good therapeutic agent at present.

4. Aphids and other parasites

The severity of insect pests such as aphids is mostly concentrated in the later stage, and the early recovery is attached to a relatively dark place, so it is difficult to find it if you do not look carefully, and the impact of batch formation is in the later stage. The disease turns out to be yellowing in the plant, and the growth rate of the disease is obviously slower than normal, which requires more inspection of the backlight area. The 2000 times solution of 25% Jule mixture is a more effective agent to inhibit such pests, and the weeds removed after the disease should be brought out of the planting area in time.

These are some of the more common disease and pest control methods of asparagus. For such diseases, we can not hold the mentality that the number of such diseases is small, and we can restore the plants themselves, which can easily lead to significant economic losses in the later stage. Once found, don't take any chances, just deal with it.
