Loofah pest control

Loofah pest control

We will also encounter various diseases in the process of growing loofah, so how can we better prevent and control them at this time?

【Blossom rot, cotton blight】:

Under high temperature and high humidity conditions, flower rot or cotton blight can cause flower rot. Vegetable farmers can choose to spray foliar agents such as Kelu, Anke, and Ridomil, or add some of the agents to the flower dipping medicine to prevent and control diseases. In addition, you may want to try the following flower dipping medicine recipe: Taking 4 catties of water as an example, in winter, you should add 3 packs of Zugualing, 2 bottles of naphthaleneacetic acid, 10 ml of 2,4-D, 1 flower bud protector, 12 ml of luffa straight flower protector, 15 ml of green source, and 1 bottle of rot spirit.

Loofah pest control

【powdery mildew】:

1. Choose disease-resistant (tolerant) varieties, such as Lvwang Loofah, Xiatang No. 1 Loofah, etc.;

2. Implement crop rotation, plant at a reasonable density, clear ditches and drain waterlogging, apply more phosphorus and potassium fertilizers, avoid nitrogen fertilizers, remove diseased leaves and burn them in batches at the early stage of the disease;

3. Chemical control: Prevention is the main method. Spray 25% Amicid suspension 1500 times at the early growth stage, flowering stage, and fruiting stage. You can also use 27% high-lipid film emulsion 80-100 times to spray the leaves at the early stage of the disease to form a protective film to prevent the disease. If you find sporadic small powder spots on the leaves, you should immediately apply pesticides for prevention and control. You can spray 10% Shigao water-dispersible granules 2000 times, 40% Miebingwei suspension 500 times, 20% Fenbuxin emulsifiable concentrate 1000 times, Fenbuxin 600-800 times, 25% Baike emulsifiable concentrate 2000 times, Bailitong 2000 times, alternately, once every 5-7 days, for 2-3 times in a row. Since melons are more sensitive to sulfur in the high temperature in summer, the concentration of sulfur-containing fungicides should not be too high, and try before use.

【Bemisia tabaci】:

1. Remove weeds from the field and eliminate their intermediate hosts and breeding bases;

2. Chemical control: Spray 7500 times of 25% Acta water dispersible granules, or 4000 times of Uranus emulsifiable concentrate, 500-1500 times of Diphid, and 1500 times of Supusha, alternately, once every 7-10 days, for 2-3 times in a row. It is best to spray adjacent fields at the same time.

Melon silk borer:

The larvae begin to cause damage in May, with large numbers occurring from July to September and causing the most serious damage.

Prevention and control methods: Remove the rolled leaves in time during the larval outbreak period to eliminate the larvae and pupae hiding in them;

Spray pesticides in time for prevention and control during the peak period of larvae, such as 1500 times dilution of 5% Metformin EC, 1000 times dilution of 52.25% Nongdi Le EC, 1000-2000 times dilution of 5% Kasik EC, 1000 times dilution of 50% Fenpyrothione EC. Use alternately.
