Loofah flowers also need to "freckle"? !

As the weather gets warmer, many summer ripe vegetables have entered the flowering stage, waiting for the harvest to go to the table~

However, the loofah often has symptoms of burnt flowers during the flowering period, which makes the vegetable farmers worry.

What is the solution?

Experts come to answer you!

Loofah burnt flowers mainly appear dry and rotten, wet rotten, flower head rot and so on.

Dry

- The edges of the petals appear dry and the entire petals are not fresh.

cause

This may be caused by blight, which is more severe in low light conditions, especially after cloudy days.

treatment method

Spraying thiophanate-methyl or Dasheng can be used to reduce the occurrence of diseases.

Water rotten

- Water rot from the edge of the petals. In severe cases, the petals appear to drip, sometimes smelly, sometimes without white mold.

cause

The case of odorous but not long hair may be bacterial soft rot, and the white mold may be flower rot or plague, both of which are heavier in high temperature and high humidity.

treatment method

Bacterial soft rot can be sprayed with streptomycin, neomycin, or can be sprayed with crown bacillus. Flower rot and plague can be sprayed with sera, dextromirer and other agents, or some agents can be added to the anthers of cockroaches.

Flower head rot

- The stigma of the flower appears black rot, and the flower will also rot.

cause

This is related to poor absorption of roots or uncoordinated water supply, or it may be caused by lack of elements such as boron and calcium in the soil.

treatment method

Foliar application of foliar fertilizer containing elements such as boron and calcium, such as Lufenwei No. 3 or No. 2, capped calcium, calcium nitrate, etc., can also be applied to some calcium fertilizer; at the same time, attention must be paid to rooting and strengthening. The absorption capacity of the root system can be increased by applying humic acid or microbial fertilizer, or by mixing certain rooting agents with thiophanate-methyl, carbendazim, ethylphosphonium, aluminum, manganese, and the like. Each plant is about 0.25 kg.

Black mold

- There are black mildew spots on the flowers.

cause

Mostly caused by coal mold.

treatment method

It can be sprayed with thiophanate-methyl 500-fold or 800-fold.

I. Introduction
Papermaking dry strengthen agent is our company`s new and self-developed products that using imported raw materials. Its mechanism of action is: Dry Strength Agent use polymer mesh structure to increase hydrogen bonding number in the mutual area of fiber to fiber. Dry strength agents in the combination area of long-chain polymers can be deformed, thus increasing the bond toughness. It could improve paper strength by the bridging ability formed by chemical function to make fibers and fibers have "implicated"

II. Technical indicators

III. Function

     The dry strength agent is not only a good enhancement, but it also has a higher enhancement effect in waste papers with more fine fiber filler. The use of our dry strength agent can improve paper quality, and it also significantly increase production efficiency, reduce costs and increase economic efficiency.

IV. Method of Application and Notes

1. When diluted with clean water, the dilution multiples of our product is generally about 15 to 30 times. After the product was stirred sufficiently, add uniformly to the slurry in an amount of 5 ~ 10 kg / ton.

2. Adding position that selected could have a full contact with the slurry. Generally choose ingredients pool, high box or import pump.

3. Use a plastic or stainless steel as the material for products storage, dilution tank, piping etc.. Iron-based material will produce corrosion and thickening phenomenon will occur.

4. Do not mix with Other Chemicals.

V. Packing

      1000 kg barrels, or according to user requirements.
