What happened to my cucumber plant

Sali sir any way to save these plants? Should I plant them in fresh soil? And please tell proportion of trichoderma to use in soil?

Meha Kabra Transplant the healthy ones to bigger pots immediately and treat the soil with copper oxychloride wettable powder before planting.

Sali sir kindly explain how to treat soil with copper oxychloride powder.. for the time being (till I get this powder) can I plant them in some other healthy plants pot?

Meha Kabra First spray copper oxychloride or Metalaxyl. If it cures, then no need to use Trichoderma. I'm referring it to Venkat Pawar because he can help about cucumber Damping-Off of Seedlings.. Referred to Venkat Pawar., pls help him to save the seedlings.

Meha Kabra Spray Aliette2 gm per litre. Sharing pic for your information

Sali Venkat Pawar. Thank you for the help. I wish this could save my plants.

Yes, of course, shift the healthy plants to new pot and treat the soil and base of the plant by spraying copper oxychloride wettable powder 2 g/ litre of water. Thank you for asking once again😂

Sali thank you sir

Hi Meha Kabra Agreed with diagnosis bySali sir Please follow the instructions as already said bySali sir And Venkat Pawar. Sir

Great efforts Sali sir and Venkat Pawar. Sir.🙂🙂

Meha Kabra Please also go through this detail: Cause:  Several fungi or fungus-like microorganisms incluing Pythium ultimum,  Fusarium sp.,and Rhizoctonia sp., which live in soil and attack seedlings of many different crops. As seedlings mature, they become resistant to attack. The disease can be a serious problem in cool, wet soils. Symptoms: Seedlings may be attacked before or after emergence, resulting in gaps and uneven stands. Young plants suddenly wilt and topple over. Water-soaked lesions are apparent on stems at the soil line for only a short time before the seedling dies. Cultural control Planting after soil warms speeds seedling growth and emergence. Mulch to increase soil temperature. Plant shallowly to promote quick emergence and growth. Avoid using old seed, which may not emerge quickly.

Some of Biological controls: Actinovate AG at 3 to 12 oz/A as a soil drench at planting. Actinovate Lawn & Garden at 1/2 to 1 teaspoon/gal water.  Cease at 4 to 8 quarts in 100 gal water applied to soil at 1 pint/sq ft for each 3-inches of soil depth on 21- to 28-day intervals. For greenhouse plants only. Double Nickel LC at 0.5 to 4.5 pints/A for soil application on 14- to 28-day intervals. Can be applied the day of harvest. Prestop at 1.4 to 14 oz/10 gal water (0.1% to 1.0% suspension) as a soil drench or incorporation into growing medium. Rootshield Home and Garden at 1 to 3 Tbsp/gal water as a soil drench at planting.  Rootshield WP at 3 to 5 oz/100 gal water for greenhouse soil drench and field chemigation or at 16 to 32 oz/A as an in-furrow spray. SoilGard 12G at 0.5 to 10 lb/A at 4-week intervals will suppress Pythium and Rhizoctonia. See label for specific application types and timings. Can be applied on the day of harvest.  Stargus at 3 to 4 quarts/A as a soil drench on 10- to 21-day intervals. Preharvest interval is 0 days. Hope this information helps you 🙂 🙂 Thanks for using the plantix community 🙂🙂

Fuzail Sali Venkat Pawar. They all died overnight (except 2). Can you please tell precautions which I should take before starting with new seeds so that this not happen again. It hurts badly when plant dies.

Sali Fuzail Venkat Pawar. Kindly guide me how to treat soil mix by fungicide before sowing seeds and some precautions as I am beginner need guidence. What if our soil mix gets contaminated, how to treat that.

Meha Kabra Go through this information: Fungus exists naturally in soil, and most of it’s beneficial for your plants. But there are 8,000 varieties that have no purpose other than messing up your garden plants. They spread sickness like root rot that infects plant roots and keeps them from drawing water and nutrients into the plant. Stem, collar and crown rots hit the plant at ground level, where it touches the soil. Then there’s good old wilt disease that, no matter how much water you give your plants, leaves them as droopy as one of those melted clocks in a Dali painting. Damping off disease slays seedlings, causing them to die suddenly just after they germinate. To get rid of fungus in potting soil, just take 1 part of hydrogen peroxide and 9 parts of water and mix well . The mixture can be used twice a day and don't sprinkle on leaves of plant but spray it only on potting soil.

Meha Kabra Read about application of Baking soda. Popular antifungal agents contain copper and sulfur, which are both toxic materials. These chemicals can be used indoors, however safety instructions must be followed very carefully. These chemicals are toxic to mammals, so avoid ingesting them and wear protective clothing when applying them to your plants. If any pets or children will be interacting with the treated plants, it may be best to avoid using these chemicals or move the plants to a location where they cannot be disturbed.  If you prefer a gentler solution, try using baking soda. Baking soda (sodium bicarbonate) is an antifungal agent and can even kill some established forms of fungus. Research has shown it's effective against some kinds of black spot and powdery mildew. Best of all, baking soda is completely non-toxic for mammals, readily available in any grocery store, and inexpensive.  Making the Spray Make a typical baking soda spray by dissolving 1 teaspoon of baking soda into one quart of water. You can add a few drops of insecticidal soap or liquid soap to help the solution spread and stick to the leaves. Only use liquid soap, like Ivory, and not laundry detergent. Stir this mixture around and then pour it into a clean, empty spray bottle. You can also one tablespoon Neem oil for Good results. Spray the plant completely, reaching both the upper and lower leaves, and let the plant dry. Repeat the application as necessary to control the fungal problem. If the fungus continues despite the repeated application of baking soda, consider using a stronger antifungal agent. Baking soda sprays should be labeled and stored out of reach of children. If you have leftover spray, it can be left sealed and used next time. Give the spray bottle a gentle shake prior to use.  Don't use too much concentrated solutions of baking soda for longer periods as it may limit the growth of plant.

Prevention Tips Use a sterile potting mix, rather than soil from your garden. The funguses and molds that cause damping off can live in the soil and outdoor garden soil can harbor all kinds of fungus spores. Start with clean pots. Even the small amount of soil clinging to plant pots is enough to provide a safe harbor for fungal spores. If reusing pots, sterilize in 1 part bleach to 10 parts water. Plant your seeds at the proper depth so they don't have to work so hard to germinate. Don’t bury the plant’s crown. Don’t crowd your seedlings. Be sure to leave room between them for air circulation. Fungal diseases and mold favor damp conditions. Water seedlings from the bottom, by placing the container in a tray of water. This keeps the seedling itself dry and less susceptible. Add a thin coating of sand or gravel on top of the potting soil, to keep the surface relatively dry. The soil underneath will remain moist, even if the sand or gravel dries out. Don’t overwater your seedlings or leave them sitting in water. Drain off any excess. If possible, create a breeze by placing a small fan nearby and turning it on periodically each day. This will prevent humidity from settling on your seedlings. Give your seedlings plenty of heat and light, so they germinate and grow quickly. Damping off only affects seedlings. If you can get them past the seedling stage, they're safe.

Fuzail thanks a lot...will implement with next batch of seeds.

You're most welcome Meha Kabra 🙂🙂
