Common diseases and insect pests in strawberry planting and their control methods

Pest control is a common problem in strawberry cultivation. What are the common diseases and insect pests in strawberry? What methods and pesticides can control these diseases and insect pests? Let's take a look at it.

Main insect pests: red spiders, aphids, grubs, ground tigers, etc.

Main diseases: Botrytis cinerea, powdery mildew, bud blight.

1. Botrytis cinerea: an important disease in spring.

Control measures: diseased fruits, diseased inflorescences and withered, old and diseased leaves were removed and destroyed by ① at any time. During the period of ② shedding, the film should be uncovered to reduce humidity, dredge the ditch system, and drain in time after rain. Before covering the plastic film and before and after the plastic shed, ③ sprayed 50% topiramine wettable powder 700 times 800 times or 50% carbendazim wettable powder 1000 times, or 50% Shu Ke Lin 2000 times, respectively.

2. Powdery mildew

Prevention and control methods: at the initial stage of the occurrence of the disease, the early diseased fruit was removed in time with 25% chlorpheniramine 2000-3000 times, or 70% methyl topiramate 700 times, or 50% acetaminophen 800 times, and destroyed centrally.

3. Red spider

Prevention and control methods: 20% scavenging profit 2000 times, 10% synergistic pyrethrin 1000 times.

4. Aphids

The density is the highest in early summer and early autumn. Aphids can spread strawberry virus and cause viral diseases. 50% aphid spray wettable powder 2000-3000 times, or 50% aldicarb 3000 times and other chemical spray control.

Special hint

It is strictly forbidden to use highly toxic pesticides such as carbofuran, methamidophos, monocrotophos, DDT, 1605, 1059, 401 on strawberries; give priority to the use of biological pesticides, scientifically use chemical pesticides with high efficiency, low toxicity and low residues, and pay attention to the safe interval between pesticide application and harvest to produce high-quality pollution-free strawberries.
