Cucumber, grape downy mildew, commonly known as “runner’s stem”, “dry leaves”, seedlings can be affected by adult plants, mainly affecting the leaves and stems, tendrils and pedicels are less affected. Cucumber, grape growth plays an important role in the impact of downy mildew, directly related to the cucumber, grape production, then how to control downy mildew? Today, I would like to introduce you to a special drug for the prevention and control of downy mildew, which is enoylmorpholine.

1、Product characteristics

Allylmorpholine is mainly from the following three aspects of the role of the fungus: prevention, can prevent the germination and invasion of the spores of the fungus; therapeutic effect, can penetrate into the plant tissue, kill the fungal mycelium; anti-spore effect, to prevent the formation of spores of the fungus, reduce the source of infestation.

This unique mechanism of action and the characteristics of multiple stages of action, so that enoylmorpholine has excellent control effect on downy mildew and epidemic disease.

(1) Good effect and long duration of action

Allylmorpholine mechanism of action is unique, effective in the oomycete fungi of all stages of reproduction, on a variety of downy mildew and epidemics have special effects. Both preventive effect and therapeutic treatment, and anti-spore-producing effect.

Allylmorpholine application interval is usually about 7-10 days, 3-4 days longer than other agents, long duration, reducing the number of times to use, saving time and costs.

(2) No drug resistance

Allylmorph and other fungicides such as mefenoxam and cyanogen have no cross-resistance, and mixed with strong, can quickly kill the fungus resistant to other fungicides to ensure stable efficacy.

(3) Resistant to rainwater erosion

Super water solubility and dispersion, strong penetration, can quickly penetrate the leaves and local diffusion, rainwater resistance, spraying 1 hour after the rain effect is almost unaffected.

Enhance plant photosynthesis, make fruits and vegetables brighter and improve crop yield and quality.

(4) Good compounding property

Allylmorph can be compounded with azoxystrobin, pyrimethanil, fenoxycarb, manganese zinc, zinc propanil, ethamethoxam, fomesan, chlorothalonil, aluminum triethylphosphonate, pyrazole ether, aminooligosaccharide, methomyl, methomyl, mesophosgene, isomethoxamate, etc.

(5) Good safety

Even in the flowering period and fruit expansion period, allylmorpholine is also very safe.

2、Applicable scope

Grapes, lychees, cucumbers, melons, bitter melons, tomatoes, peppers, potatoes, cruciferous vegetables.

Enoylmorpholine has good control effect on downy mildew, fungal disease, late blight, epidemic (mold) disease, epidemic rot, rot, black tibia and other low fungal diseases. In vegetables can control cucumber downy mildew, melon downy mildew, taro blight, pepper blight, cruciferous vegetables downy mildew, etc.

Allylmorpholine formulations are 25%, 30%, 50% wettable powder, 25% microemulsion, 10%, 20%, 40%, 50% suspension, 40%, 50%, 80% water dispersible granules, 50% blister tablets, 10%, 15% water emulsion.

Apply once at 7-10 days interval, alternating with different types of agents, focusing on spraying the back of the leaves, 3 times in a row.

(2) Control pepper blight. Start to apply before or at the beginning of the disease, using 30-40 grams of 50% wettable powder per mu and spraying with 50-75 water. Depending on the development of the disease, apply the drug once at an interval of 5-7 days and 3 times continuously.

(3) Control late blight of tomato. At the early stage of the disease, use 40-60g of 50% wettable powder and spray with 40-50kg of water.

(4) Prevention and control of tomato blight root rot. At the beginning of the disease, pour 2000 times of 50% wettable powder or 1000 times of 50% aminopyralid water dispersible granule mixed with 750 times of 50% enoylmorpholine water dispersible granule.

(5) Control potato late blight. Start spraying at the early stage of the disease with 50% wettable powder 1000 times. 7-10 days spray 1 time, alternating with different types of agents.

(6) Control of lettuce downy mildew. Spray with 50% wettable powder 1000 times at the beginning of the disease. 1 time in 7-10 days, about 2 times in a row, focusing on the back of the leaves.

(7) control cruciferous vegetables downy mildew. Each mu with 80% water dispersible granule 20-25 grams or 50% wettable powder, 50% water dispersible granule 30-40 grams, 40% water dispersible granule 30-40 grams, 25% wettable powder 40-60 grams, 10% water emulsion 100-150 ml, mixed with 30-45 kg of water spray.

(8) Control seedling blight, sudden collapse disease and stem base blight of melon and fruit vegetables. From the first sight of the disease plant with the liquid watering (or spraying) seedbed or plant stem base, about 10 days once, 2 times in a row. Generally use 80% water dispersible granule 2000-3000 times or 50% wettable powder, 50% water dispersible granule 1500-2000 times, 40% water dispersible granule 1000-1500 times, 10% water emulsion 300-400 times.

(9) Control melon, eggplant and fruit, leafy vegetable crops diseases. Generally use 35-50 grams of active ingredient per mu and spray with 30-60 kg of water. The effect is good before the occurrence of the disease or when the disease spot is first seen.
