b. Control vegetative growth to increase yield
| Rice | In the late stage of diversity (7d before jointing), rice was sprayed with 100~150mg/L of enlobuzole to promote tillering, dwarfing and increasing yield. |
| Wheat |
In the early stage of jointing, the whole plant of wheat was sprayed with 50-60 mg/L enlobuzole, which could control the elongation of internode, increase the anti-lodging ability, increase the effective spike, thousand grain weight and grain number per spike, and promote the yield increase. |
| Sweet sorghum | When the plant height of sweet sorghum was 120cm, 800mg/L of enlobuzole was applied to the whole plant, the stem diameter of sweet sorghum was increased significantly, the plant height was decreased significantly, the lodging resistance was increased, and the yield was stable. |
| Millet | At the heading stage, applying 30mg/L liquid medicine to the whole plant can promote the strengthening of the rod, prevent lodging, and increase the seed density with appropriate amount can significantly promote the yield increase. |
| Rape | At the early stage of bolting to the height of 20cm, the whole plant of rape can be sprayed with 90~125 mg/L of liquid medicine, which can make the leaves dark green, leaves thickened, plants significantly dwarfed, taproot thickened, stems thick, effective branches increased, effective pod number increased, and promote yield increase. |
| Peanut | In the late flowering period of peanut, spraying with 60~120 mg/L liquid medicine on the leaf surface can effectively control the growth of peanut plants and increase the flower production. |
| Soya bean | In the early stage of soybean branching, spraying with 25~60 mg/L liquid medicine on the leaf surface can control plant growth, promote the increase of stem diameter, promote pod formation and increase yield. |
| Mung bean | Spraying with 30 mg/L liquid medicine on the leaf surface of mung bean at the inking stage can control plant growth, promote leaf physiological metabolism, increase 100 grain weight, grain weight per plant and grain yield. |
| Cotton | At the early flowering stage of cotton, leaf spraying with 20-50 mg/L liquid medicine can effectively control the length of cotton plant, reduce the height of cotton plant, promote the increase of boll number and boll weight of cotton plant, significantly increase the yield of cotton plant, and increase the yield by 22%. |
| Cucumber | In the early flowering stage of cucumber, the whole plant was sprayed with 20mg/L of liquid medicine, which could reduce the number of segments per plant, increase the rate of melon formation, effectively reduce the first melon segment and deformity rate, and significantly increase the yield per plant. |
| Sweet potato, potato | Applying 30~50 mg/L liquid medicine to sweet potato and potato can control the vegetative growth, promote the expansion of underground potato and increase the yield. |
| Chinese yam | In the flowering and bud stage, spraying the yam with 40mg/L liquid once on the leaf surface can significantly inhibit the daily elongation of the overground stems, the time effect is about 20d, and can promote the yield increase. If the concentration is too high or the number of times is too much, the yield of the underground part of yam will be inhibited while the elongation of the stems above ground is inhibited. |
| Radish | When three true radish leaves were sprayed with 600 mg/L liquid, the ratio of carbon to nitrogen in radish leaves was reduced by 80.2%, and the budding rate and bolting rate of plants were reduced effectively (decreased by 67.3% and 59.8%, respectively). The use of radish in spring counterseasonal production could effectively inhibit bolting, prolong the growth time of fleshy roots, and improve economic value. |
c. Control the growth of branches and promote flower bud differentiation
In the summer shoot period of citrus, 100~120 mg/L enlobuzole solution was applied to the whole plant, which could inhibit the shoot length of citrus young trees and promote fruit setting.
When the first batch of male flowers of litchi flower spike opened in a small amount, spraying with 60 mg/L of enlobuzole could delay the flowering phenology, prolong the flowering period, significantly increase the number of male flowers, help to increase the initial fruit set amount, significantly increase the yield, induce the seed abortion of fruit and increase the rate of scorch.
After secondary core-picking, 100 mg/L of endosinazole combined with 500 mg/L of Yiyedan was sprayed twice for 14 days, which could inhibit the growth of new shoots, reduce the length of jujube heads and secondary branches, increase the coarser, compact plant type, enhance the fruit load of secondary branches and enhance the ability of jujube trees to resist natural disasters.
d. Promote coloring
Apples were sprayed with 50~200 mg/L liquid at 60d and 30d before harvesting, which showed significant coloring effect, increased soluble sugar content, decreased organic acid content, and increased ascorbic acid content and protein content. It has good coloring effect and can improve the quality of apples.
