How to solve the problem of Lycium barbarum pests and diseases?

Disease and pest control: Lycium barbarum L. has a strong resistance to stress, and pests and diseases rarely occur. The main diseases of Lycium barbarum are black fruit disease and root rot disease. In the early stage of black fruit disease, 1:120-160 Bordeaux solution, 50% Wettable Deinococcus 1000-fold solution or 65% Wettable Deinococcus 500-fold solution can be sprayed once every 7-10 days. Root rot.
In the early stage of the disease, 50% carbendazim 1000-1500 times liquid can be used for root irrigation, or the disease plant can be immediately removed, and the soil around the disease plant can be disinfected with lime.
The main pests are fruit fly and gall mite of Lycium barbarum. When the fruit flies are harms, 90% dimethoate 800 times liquid or 40% Omethoate 1500 times liquid can be used to prevent and cure the disease. The fruit can also be harvested and buried deep. In order to prevent the occurrence of gall mites, spraying 40% times of Omethoate and 1000~1500 times liquid for 40% days, 3~4 times per 10 days.

  1. Lycium barbarum aphids
    Also called green honey, oil sweat. Harm the tender branches, leaves and young fruits, absorb juice, weaken the tree vigor and make the fruit thin and small. The spring shoot extraction period of Lycium barbarum L. from late April to early May and from mid-May to mid-late July are the critical period for the pest control. Spraying 3% acetamiprid 1500 times solution plus Emmel 1 bag/30 kg water, 2.5% Popper aphid 2000 times solution plus Emmel 1 bag/30 kg water for control.
  2. Wolfberry Psylla
    It’s also called jaundice. Adults overwinter within 90-120 cm of the main trunk under the crown. May to June is the period of nymph occurrence. The nymph is more harmful than the adult. The nymph is covered with leaves, punctures and sucks juice, and excretes large amounts of white feces, which makes the leaves yellow. The overwintering adults in early and mid-April have a large number of stings and have not yet laid eggs, which is the key period of control. From late May to mid-June, the first generation of adults, eggs or nymphs occurs at their peak. During these two periods, spraying 28% hydroamine thiocyanate 1500 times solution or 1.8% oleanidin 3000 times solution once every 10 days, spraying 2-3 times continuously.
  3. Lycium barbarum gall mite
    It’s also called nevus. When Lycium barbarum leaves were unfolded in mid-late April, adults emerged from bud axilla and scales of current or biennial branches, and gall mites migrated from old branches to new shoots from late May to early June. In these two periods, the insect body was exposed to gall, and no bulge was formed, which was the best time for spraying control. Use 800 times of gall rust mite net or 1600 times of Nisolon or 4000 times of 1.8% oleanidin every 10 days for 2 to 3 times in a row.
  4. Negative Mud Worm of Lycium barbarum
    Adults and larvae both harm leaves and gnaw on the mesophyll. In severe cases, the branches and tender leaves are eaten up and burned. From late March to early April, after shallow tillage or ploughing, 50% phoxim 1-1.5 kg and sandy soil were mixed into toxic soil to be sprayed and raked flat. In mid-April, May to September, when mud pests were harmful, spraying could also control aphids, and no additional control was needed.
  5. Lycium barbarum powdery mildew
    Usually occurs in rainy years, the onset time is from June to August. White powder is formed on the front and back of the leaves, which often causes the leaves to shrink, wither and fall off at an early stage. Spray 45% sulfur suspension 200 – 300 times or 50% tobacco 600 – 800 times every 10 days for 2 – 3 times.
  6. Lycium barbarum red gall mosquito
    Old larvae overwinter in soil cocoons under tree crowns after fruiting. Adults lay eggs in buds. Larvae endanger buds and young fruits, often causing flower and fruit drop. In late April, mid-late May and late August, 3% Alphate 2500 times solution was sprayed for control.
