I. Preface

II. Green prevention and control technology of diseases and insect pests

1. Occurrence and control of main diseases and insect pests in watermelon.

* Pest control is the most frequent and important task in watermelon field management, and it is an important measure to ensure stable yield and income increase of watermelons.

* while strengthening the management of water and fertilizer, the strategy of "giving priority to prevention and comprehensive control" should be adopted to do a good job in the control of diseases and insect pests. It is necessary to carry out frequent inspection and early prevention so as to eliminate diseases and insect pests at the initial stage.

① watermelon Fusarium wilt

Grafted watermelon also has Fusarium wilt (pumpkin rootstock, cucurbit rootstock, etc.)

Prevention and control methods of watermelon Fusarium wilt

* disinfect or disinfect seeds with disease-free seeds

* reduce humidity-no dripping film, ventilation, full film mulching

* rotation includes rotation of vegetables of different families and genera and rotation of flood and drought

* soil disinfection

* grafting

* Clean the countryside

Grafting

Soil disinfection

Prevention and control of Fusarium wilt of watermelon and muskmelon:

Available at the initial stage of the disease:

* 50% gray moldy clear WP500~800 times solution

* 30% dimethrin AS1500 doubling solution

* 50% Kuweiling WP500~800 doubling solution

* 10 billion Bacillus subtilis WP500 doubling solution

* 50% carbendazim WP500~700 doubling solution

* 10% high water dispersible granule 3000-6000 times liquid

* 9% robust suspension seed coating agent 1500-3000 times

* 42.8% Lunasson SC1000~1500 doubling solution

0.25 kg per plant, once every 5-7 days, for 2-3 times.

② low temperature waterlogging-retting root

Melon field soil

Retting root

Effects of Shi Fangli's main free amino acids on plants:

How to use it:

Combined with the use of pesticides and fertilizers, it is suggested that crops should be sprayed more than 300-600 times of leaves before and after stress to improve crop resistance and promote rapid recovery of crop growth. Melons, fruits and leafy vegetables can be transplanted at a continuous low temperature, and Shi Fang can quickly slow down seedlings and increase plant freezing resistance.

③ "Spring Root"

Prevention and control of "spring root"

* choose rootstocks with strong moisture resistance.

* in areas where conditions permit, select fields with weak soil viscosity (loose)

* the fields are trenched and drained.

* the soil should not be too wet when planting and it is best to plant it on a sunny day.

* the inner wall of the implant hole should not be smooth and rough.

* the mud sealing (planting hole) should be timely and the mud thickening should be appropriate.

Enoson-full-humic phytic acid fertilizer

Activate root soil

-improvement of rhizosphere microecology (microbial activity)

-activating medium and trace elements fixed by soil

-improve soil aggregate structure, improve water retention and reduce soil salinization.

Activated plant

-stimulate root growth

-activate cells and enhance plant metabolism

Enhance the ability of anti-freezing, drought and saline-alkali resistance.

After watching the growth, look at the root system.

The effect of Enoson on watermelons:

* slow down the seedlings quickly

* promote root system (Baigenduo)

* Resistance to root frost injury

* too many flowers and high fruit setting rate

* listing ahead of time

The effect of Enoson on the soil:

* looser soil

* there are many soil microorganisms.

* reduce saline-alkali moss

* less waste of fertilizer

* turn dead soil into living soil

Recommended usage of Enoson watermelon, dosage:
