Soil Conditioner

Root growth is vital for plants growth.It’s responsible for the absorption of nutrients and water, as well as controlling the physiological activities of the aboveground organs. 6 ways to stimulate plants root growth 1.Adjust the soil pH of the plough layer Unreasonable fertilization for many years leads to changes in the pH value of the plough layer, which is the root cause of today’s soil problems. Our recommendation is to use a special soil conditioner according to the actual situation after testing the pH of the plough layer. 2.Adding biological fertilizer(Such as  Trichoderma harzianum ) The application of biological fertilizer can improve the soil condition, they are suitable to be applied on soils problems with salinization,hardening and acidification.Significantly improve these soil condition and promote the growth of root system, and can control harmful bacteria and fungus or other organisms to r...

Good soil is the basic for root growth. One application of Dora Rootguard can protect crops roots away from various soil diseases for 3 months. Dora RootGuard is trichoderma harzianum biological fungicide for eliminating damaging fungal pathogens, such as Phytophthora, Rhizoctonia, Pythium, Fusarium.It will form a nature defensive bond to “Guard” your crop’s roots. One Application provides 2-3 months root system protection against soil borne diseases. More info of Dora rootguard: www.doraagri.com/product/dora-rootguard/

Bacillus subtilis grows fast.It can produce heat-resistant and stress-resistant spores. It can be made into various dosage forms. It can be mixed with chemical pesticides without inactivation, and the mass production process is simple, the cost is low, and the application is convenient and storage. bacillus subtilis The effects of Bacillus subtilis on plants are mainly reflected in the following aspects: 1.Nutrition and space competition The competitive effects of Bacillus subtilis mainly include nutritional competition and spatial locus competition. It can rapidly and massively multiply and colonize in the rhizosphere, body surface or in the soil and in the soil, effectively reject, prevent and interfere with the colonization and infection of plant pathogenic microorganisms on plants, thereby achieving antibacterial and disease-preventing effects. 2.Produce antibacterial substances Bacillus subtilis can produce a variety of substances with antibacteria...

2018 Agroexpo Bogota In 2018,many countries begin to attach importance to environmental protection,then many traditional pesticides are forbidden to sale. From 2017,Dora Agri foucs on biocontrol solution to reduce the use of traditional pesticides and fungicides.Now great progress has been made in research on biocontrol solution. If you have interest,Please kindly check the our  biocontrol  and  biofertilizer  series.Hope our information will be useful for you,and we are willing to hearing from your reviews.

Early blight  and  late blight  are important diseases on solanaceous vegetables.Although the names of the two diseases are only one word difference,some vegetable farmers do not know exactly about early blight and late blight.Some people even think that the two diseases are only happening time different. There are many problems in the prevention and treatment of diseases.Especially in the selection and use of chemical fungicide,blind drug use not only does not play a role in disease prevention,but delays the best prevention and control time,leading to serious diseases. early blight and late blight What’s difference between early blight and late blight? Early blight  mainly affects the stems,leaves,and fruits of vegetables,and is most susceptible to disease at the branches of leaves and stems.At the seedling stage,the base of the stem of the seedlings is dark brown lesions,slightly sunken,and has a ring pattern.The onset of adulthood generally develops...

grape magnesium deficiency What’s symptom of grape magnesium deficiency?The leaves are chlorotic.Because magnesium can be transferred to young parts in plants,the top leaves are asymptomatic. Initially starting from the base blade,the leaf edge turns yellow first,the leaves are water-stained,and the yellow veins are severe. General reasons 1.The soil is mostly acidic,the pH value is too low,the magnesium leaching is serious,the release of magnesium is obviously inhibited,and the average content of exchangeable magnesium in the soil is lower than the critical level,and the magnesium deficiency is serious. 2.Grapes are potassium-producing crops,but excessive potassium inhibits the absorption of magnesium by the roots of the grapes and transports magnesium ions to the above-ground parts,causing magnesium deficiency. 3.Magnesium and calcium,ammonium ions also have antagonistic effects,therefore,the soil calcium content is too high or the application of calcium and nitrog...

 There are some disease during watermelon plantation,especially in the old melon area where continuous cropping.Recently,many farmers have consulted about the problems related to watermelon disease.Here we sort out watermelon diseases identification and hope it is useful to everyone. Occurrence period : mainly harm unseeded and freshly emerged seedlings. Identification points : stem base rot, seedlings tripped, white hyphae when high humidity. Occurance period : whole growth period Identification point :1.leaf, brown spotted,slightly depressed,yellow external halo,unaffected by veins, perforated when dry. 2.Fruit,The lesion starts dark green and becomes dark brown,and cracks can occur.   Occurence period : late growth period Identification point : lesion becomes from light green to yellow, and then brown, restricted by veins, mildew when wet.   Occurence period :whole growth period Identification point : 1.Leaf, from the edge of the leaf, it...
